📖 Breakdown
Amud Aleph (28a)
Segment 1
TYPE: דיחוי קושיא
Continuation of the dam challenge from 27b. The Gemara had proposed that the baraita’s case of someone “needing the blood” refers to a bird — proving birds require shechita. Now the Gemara rebuts: the case is really a chayah, where the blood is needed as red dye.
Hebrew/Aramaic:
מַאי לָאו בְּעוֹף, דְּקָא בָעֵי לֵיהּ לִדְמֵיהּ לְיָנִיכָא? לָא, בְּחַיָּה דְּקָא בָעֵי לֵיהּ לִדְמֵיהּ לְלַכָּא.
English Translation:
What, is it not referring to a bird, as he requires its blood to remove a moth from his garments? If so, apparently birds require slaughter by Torah law, as, if that were not the case, then even if a bird were stabbed, covering of the blood would be required. The Gemara rejects that proof: No, the baraita is referring to an undomesticated animal, as he requires its blood to use as a red dye [lelakka] Therefore, no proof may be cited from this baraita that birds require slaughter by Torah law.
קלאוד על הדף:
The Gemara picks up the second challenge from yesterday’s mnemonic (dam). The baraita on 27b spoke of someone who “needs the blood” — and the Gemara had suggested this refers to a bird whose blood is harvested for yanikha (a household use, removing moths from clothing, per Rashi). If birds were biblically exempt from shechita, then nechirah of a bird should also count as “shechita” for kisui-purposes, and the baraita’s exemption from kisui would be untenable. The Gemara now neutralizes the challenge by reassigning the case to a chayah (undomesticated animal) — where the blood is wanted as lakka, red dye. Since chayah unambiguously requires shechita, the baraita supplies no proof for or against the status of bird-slaughter.
Key Terms:
- לְיָנִיכָא (lelyanikha / le-yanikha) = For use against clothes-moths (per Rashi) — a household use of blood that was a candidate for the baraita’s “need.”
- לְלַכָּא (lelakka) = For red dye (lak) — a textile-dyeing use; reassigning the case to chayah neutralizes the challenge.
Segment 2
TYPE: תא שמע — קושיא שלישית
Third challenge from the mnemonic (bi-melika) — a Mishna in Zevachim 68a: a bird-offering whose nape was cut with a knife (instead of pinched with the thumbnail) imparts impurity at the throat-stage, proving that knife-cutting did NOT save the bird from nevelah-status.
Hebrew/Aramaic:
תָּא שְׁמַע: מָלַק בְּסַכִּין, מְטַמֵּא בְּגָדִים אַבֵּית הַבְּלִיעָה. וְאִי אָמְרַתְּ אֵין שְׁחִיטָה לָעוֹף מִן הַתּוֹרָה, נְהִי נָמֵי דְּכִי תָּבַר לֵיהּ שִׁדְרָה וּמַפְרֶקֶת הָוְיָא לַהּ טְרֵפָה, תַּהְנֵי לַהּ סַכִּין לְטַהֲרָהּ מִידֵּי נְבֵלָה!
English Translation:
The Gemara cites proof from a mishna (Zevaḥim 68a): Come and hear: If one cut the nape of the neck of a sacrificial bird with a knife instead of pinching it with his fingernail, this bird carcass renders the garments of one who eats the bird ritually impure when the meat is in his throat. The Gemara explains the proof: And if you say that slaughter of a bird is not obligatory by Torah law, then although when cutting the bird from the nape, he breaks the spine and the neck bone with the knife before severing the gullet and windpipe, and it indeed becomes a tereifa and may not be eaten, cutting the simanim with the knife should be effective to purify it, i.e., to prevent it from assuming the status of an unslaughtered carcass. The fact that the garments of one who swallows the meat of the bird become ritually impure indicates that slaughter is the only method effective in permitting the consumption of a bird and for preventing it from assuming the status of an unslaughtered carcass.
קלאוד על הדף:
The third and apparently strongest challenge to Rabbi Yitzchak ben Pinchas (the bi-melika item in the mnemonic). A korban bird must be killed by melika (pinching with the priest’s thumbnail) — using a knife instead invalidates the offering. The Mishna in Zevachim 68a rules that such a knife-pinched korban bird is treated as nevelah and transmits tumah at the throat-stage. Now: if bird-slaughter were not biblical, the knife should at least have functioned as ordinary shechita on the simanim and saved the bird from nevelah-status — even though the spine-and-mafreket were already broken (rendering it a tereifa). The fact that the bird stays at full nevelah-tumah proves that only proper shechita (here: melika) saves a bird from nevelah — implying shechita-for-birds is biblical.
Key Terms:
- מָלַק (malak) = Pinched (the korban-bird method) — done with the priest’s thumbnail at the nape (mi-mul oref).
- שִׁדְרָה וּמַפְרֶקֶת (shidra u-mafreket) = The spine and the cervical vertebra — cutting them is forbidden (yields tereifa). The knife-melika necessarily breaks them while pinching the nape.
- בֵּית הַבְּלִיעָה (beit ha-beli’ah) = “The throat-stage” — a nevelah-of bird transmits tumah uniquely while in the throat of one who swallows it.
Segment 3
TYPE: דיחוי — תנא תומך
The Gemara doesn’t refute the proof but rather identifies R’ Yitzchak ben Pinchas’s Tannaitic backer: Rabbi Elazar HaKappar Be-Rabbi. Introducing his derivation from “ke-asher ye’achel et ha-tzvi.”
Hebrew/Aramaic:
הוּא דְּאָמַר כִּי הַאי תַּנָּא, דְּתַנְיָא: רַבִּי אֶלְעָזָר הַקַּפָּר בְּרַבִּי אוֹמֵר: מָה תַּלְמוּד לוֹמַר ״אַךְ כַּאֲשֶׁר יֵאָכֵל אֶת הַצְּבִי וְגוֹ׳״? וְכִי מָה לָמַדְנוּ מִצְּבִי וְאַיָּל מֵעַתָּה?
English Translation:
The Gemara rejects that proof: Although it is clear from that mishna that slaughter of birds is obligatory by Torah law, Rabbi Yitzḥak ben Pineḥas states his opinion in accordance with the opinion of that tanna who holds that it is not obligatory by Torah law, as it is taught in a baraita that Rabbi Elazar HaKappar, the distinguished Sage, says: What is the meaning when the verse states: “However, as the gazelle and as the deer is eaten, so shall you eat of it” (Deuteronomy 12:22)? And what now have we derived from the gazelle and the deer with regard to disqualified consecrated animals?
קלאוד על הדף:
The Gemara concedes the content of the Zevachim mishna but neutralizes it as a binding precedent: R’ Yitzchak ben Pinchas holds like a particular Tanna who rejects the Zevachim mishna’s premise. That Tanna is Rabbi Elazar HaKappar Be-Rabbi. The Gemara introduces his derivation from a curious verse in Devarim 12:22 — “ach ka-asher ye’achel et ha-tzvi” — which compares deer/gazelle (chayah) to pesulei ha-mukdashin. The verse’s purpose seems mysterious: what would deer have to teach us about disqualified offerings? The next segment unpacks the answer.
Key Terms:
- רַבִּי אֶלְעָזָר הַקַּפָּר בְּרַבִּי (Rabbi Elazar HaKappar Be-Rabbi) = A late Tanna of R’ Yehuda HaNasi’s generation; “Be-Rabbi” is a distinguishing epithet meaning “the distinguished” / “the son of Rabbi.”
- כַּאֲשֶׁר יֵאָכֵל אֶת הַצְּבִי (ka-asher ye’achel et ha-tzvi) = Devarim 12:22 — the verse that equates the consumption of pesulei ha-mukdashin to that of deer/gazelle.
Segment 4
TYPE: דרשת רבי אלעזר הקפר
The verse’s bidirectional teaching: it teaches deer/gazelle from pesulei ha-mukdashin (both need shechita), but conspicuously omits birds — leaving bird-shechita to rabbinic legislation only.
Hebrew/Aramaic:
הֲרֵי זֶה בָּא לְלַמֵּד וְנִמְצָא לָמֵד, מַקִּישׁ צְבִי וְאַיָּל לִפְסוּלֵי הַמּוּקְדָּשִׁין: מָה פְּסוּלֵי הַמּוּקְדָּשִׁין בִּשְׁחִיטָה – אַף צְבִי וְאַיָּל בִּשְׁחִיטָה; וְעוֹף אֵין לוֹ שְׁחִיטָה מִדִּבְרֵי תוֹרָה, אֶלָּא מִדִּבְרֵי סוֹפְרִים.
English Translation:
These two undomesticated animals come in the verse to teach a halakha with regard to disqualified consecrated animals, and it is found that a halakha is derived from the case of disqualified consecrated animals in their regard. The Torah juxtaposes a gazelle and a deer to disqualified consecrated animals to teach: Just as disqualified consecrated animals are rendered fit for consumption through slaughter, so too, a gazelle and a deer are rendered fit for consumption only through slaughter. But for a bird, slaughter is not obligatory by Torah law; rather, the obligation is by rabbinic law.
קלאוד על הדף:
The classic Talmudic formula “harei zeh ba le-lamed ve-nimtza lamed” — “it came to teach, and ends up learning.” The verse compares pesulei ha-mukdashin (which obviously need shechita) to deer/gazelle, transferring the shechita-requirement to chayah. The crucial point: the verse mentions chayah but not bird. R’ Elazar HaKappar reads this as a deliberate omission — birds, conspicuously absent from this triangulation, do not get biblical shechita-status; their shechita-obligation is mi-divrei soferim (rabbinic). This is the Tanna who backs R’ Yitzchak ben Pinchas’s startling position from 27b.
Key Terms:
- מַקִּישׁ (makkish) = Juxtaposes / equates — the act of treating two cases as halakhically parallel via a textual link.
- בָּא לְלַמֵּד וְנִמְצָא לָמֵד (ba le-lamed ve-nimtza lamed) = A bidirectional juxtaposition principle: A teaches B and B teaches A.
- מִדִּבְרֵי סוֹפְרִים (mi-divrei soferim) = “From the words of the Scribes” — i.e., a rabbinic enactment, not biblical law.
- פְּסוּלֵי הַמּוּקְדָּשִׁין (pesulei ha-mukdashin) = Disqualified consecrated animals — animals dedicated to the altar but found unfit; redeemed for non-sacred use and requiring shechita.
Segment 5
TYPE: דעת רבי / מקור הלכה למשה מסיני
Rabbi Yehuda HaNasi (Rebbi) opposes Rabbi Elazar HaKappar: the phrase “ka-asher tzivitikha” in Devarim 12:21 indicates Moshe was already commanded about shechita — including bird-shechita (rov of one siman) — at Sinai.
Hebrew/Aramaic:
מַאן תַּנָּא דִּפְלִיג עֲלֵיהּ דְּרַבִּי אֶלְעָזָר הַקַּפָּר? רַבִּי הִיא, דְּתַנְיָא: רַבִּי אוֹמֵר: ״וְזָבַחְתָּ … כַּאֲשֶׁר צִוִּיתִךָ״ – מְלַמֵּד שֶׁנִּצְטַוָּה מֹשֶׁה עַל הַוֶּושֶׁט וְעַל הַקָּנֶה, וְעַל רוֹב אֶחָד בָּעוֹף, וְעַל רוֹב שְׁנַיִם בִּבְהֵמָה.
English Translation:
The Gemara asks: Who is the tanna who disagrees with Rabbi Elazar HaKappar and holds that the slaughter of a bird is obligatory by Torah law? It is Rabbi Yehuda HaNasi, as it is taught in a baraita: Rabbi Yehuda HaNasi says: The Torah states: “And you shall slaughter of your herd and of your flock, which the Lord has given you, as I have commanded you” (Deuteronomy 12:21). This verse teaches that Moses was previously commanded about the halakhot of slaughter, even though they are not written explicitly in the Torah. He was commanded about cutting the gullet and about cutting the windpipe, and about the requirement to cut the majority of one siman for a bird, and the majority of two simanim for an animal.
קלאוד על הדף:
The Gemara identifies the opposing Tannaitic view as Rebbi (Rabbi Yehuda HaNasi), the redactor of the Mishna. Rebbi anchors the rule in the trailing phrase “ka-asher tzivitikha” (“as I have commanded you”) in Devarim 12:21 — a phrase that implies Moshe had already received specific commandments earlier (at Sinai), now being referenced. The list Rebbi extracts is comprehensive: gullet, windpipe, rov-of-one for birds, rov-of-two for animals. For Rebbi, bird-shechita is biblical — it is part of the Sinai-package of shechita-halakhot. So the dispute between R’ Elazar HaKappar (rabbinic) and Rebbi (biblical) becomes the Tannaitic axis of the entire question.
Key Terms:
- כַּאֲשֶׁר צִוִּיתִיךָ (ka-asher tzivitikha) = “As I have commanded you” — the phrase Rebbi reads as referring to earlier (Sinaitic) instruction about shechita-specifics.
- רַבִּי (Rebbi / Rabbi Yehuda HaNasi) = Final redactor of the Mishna; the leading Tanna of his generation.
- נִצְטַוָּה מֹשֶׁה (nitztavah Moshe) = “Moshe was commanded” — referring to halakha le-Moshe mi-Sinai, oral commandments transmitted at Sinai.
Segment 6
TYPE: מחלוקת אמוראים
A new sub-sugya. The mishna said one siman suffices for bird-shechita — but which one? Rav Nachman: either; Rav Adda bar Ahava: only the gullet (veshet).
Hebrew/Aramaic:
אֶחָד בָּעוֹף אִיתְּמַר: רַב נַחְמָן אָמַר: אוֹ וֶושֶׁט אוֹ קָנֶה, רַב אַדָּא בַּר אַהֲבָה אָמַר: וֶושֶׁט וְלֹא קָנֶה. רַב נַחְמָן אָמַר: אוֹ וֶושֶׁט אוֹ קָנֶה – ״אֶחָד״ קָתָנֵי, ״אֶחָד״ כֹּל דְּהוּ. רַב אַדָּא בַּר אַהֲבָה אָמַר: וֶושֶׁט וְלֹא קָנֶה – מַאי ״אֶחָד״? מְיוּחָד.
English Translation:
§ The mishna teaches that in the case of one who cuts one siman in a bird, his slaughter is valid. It was stated that there is an amoraic dispute with regard to this matter. Rav Naḥman said: One may cut either the gullet or the windpipe. Rav Adda bar Ahava said: One must cut the gullet for the slaughter to be valid, but cutting the windpipe is not sufficient. The Gemara explains the formulation of the mishna according to the opinion of each amora. Rav Naḥman said: One may cut either the gullet or the windpipe. One siman is taught in the mishna, meaning that the slaughter is valid if he severs one, indicating that either siman is valid. Rav Adda bar Ahava said: One must cut the gullet for the slaughter to be valid, but cutting the windpipe is not sufficient. What is the meaning of: One, in the mishna? It means the special one, the gullet.
קלאוד על הדף:
A central practical machloket: the mishna’s “echad” (one) — which siman? Rav Nachman: either one — “echad” = any of them (whichever is cut suffices). Rav Adda bar Ahava: only the veshet (gullet) — “echad” means the special one, the meyuchad. Each reads the mishna’s elastic single word in his own register. The dispute matters: if only veshet works, a slaughterer who happens to have cut only the kaneh has performed an invalid shechita. The Gemara now launches a long series of meitivi and ta shma challenges trying to settle the question.
Key Terms:
- קָנֶה (kaneh) = Windpipe / trachea — the “respiratory” siman.
- וֶושֶׁט (veshet) = Gullet / esophagus — the “digestive” siman.
- מְיוּחָד (meyuchad) = “Special / singular” — Rav Adda’s reading of “echad” as referring to the distinguished one (veshet).
Segment 7
TYPE: סִימָן
Mnemonic for the five forthcoming proofs in the Rav Nachman / Rav Adda dispute: shachat, chatza’in, gargeret, pegima, chatat ha-of.
Hebrew/Aramaic:
(סִימָן: שָׁחַט, חֲצָאִין, גַּרְגֶּרֶת, פְּגִימָה, דְּחַטַּאת הָעוֹף.)
English Translation:
The Gemara provides a mnemonic for the proofs to be cited by the Gemara: Slaughter, halves, windpipe, deficiency, of a bird sin offering.
קלאוד על הדף:
A memory-aid previewing five attempts to resolve the veshet-or-either dispute. The five keywords map to: (1) shachat — case of slaughtering the gullet and the windpipe later being displaced; (2) chatza’in — slaughtering two half-simanim in a bird; (3) gargeret — half-windpipe followed by a pause; (4) pegima — half-windpipe pre-existing deficiency completed; (5) chatat ha-of — the procedure of pinching a bird sin-offering. Each will be brought as a ta shma.
Key Terms:
- גַּרְגֶּרֶת (gargeret) = Windpipe — synonym for kaneh.
- פְּגִימָה (pegima) = Deficiency / notch — a pre-existing cut on the siman.
- חַטַּאת הָעוֹף (chatat ha-of) = Bird sin-offering — the korban whose nape is pinched.
Segment 8
TYPE: מיתיבי — ראייה לרב אדא
First challenge (shachat) against Rav Nachman: a baraita governing displaced windpipes mentions only veshet-slaughter — implying only veshet works.
Hebrew/Aramaic:
מֵיתִיבִי: שָׁחַט אֶת הַוֶּושֶׁט וְאַחַר כָּךְ נִשְׁמְטָה הַגַּרְגֶּרֶת – כְּשֵׁרָה, נִשְׁמְטָה הַגַּרְגֶּרֶת וְאַחַר כָּךְ שָׁחַט אֶת הַוֶּושֶׁט – פְּסוּלָה, שָׁחַט אֶת הַוֶּושֶׁט וְנִמְצֵאת גַּרְגֶּרֶת שְׁמוּטָה וְאֵינוֹ יוֹדֵעַ אִם קוֹדֶם שְׁחִיטָה נִשְׁמְטָה אִם לְאַחַר שְׁחִיטָה נִשְׁמְטָה – זֶה הָיָה מַעֲשֶׂה, וְאָמְרוּ: כׇּל סָפֵק בִּשְׁחִיטָה – פְּסוּלָה, וְאִילּוּ שְׁחִיטָה בְּגַרְגֶּרֶת לָא קָתָנֵי.
English Translation:
The Gemara raises an objection to the opinion of Rav Naḥman from a baraita: If one cut the bird’s gullet and thereafter the windpipe was displaced, the slaughter is valid. If the windpipe was displaced and thereafter he cut the gullet, the slaughter is not valid. With regard to a case where one cut the gullet and the windpipe was found displaced and he does not know if it was displaced prior to the slaughter or if it was displaced after the slaughter, that was an incident that transpired, and the Sages said: In any case of uncertainty with regard to slaughter, the slaughter is not valid. The baraita mentions only the case of cutting the gullet, while cutting the windpipe is not taught. The baraita supports the opinion of Rav Adda bar Ahava and is contrary to the opinion of Rav Naḥman.
קלאוד על הדף:
The shachat item from the siman: a baraita whose entire framework is “shachat et ha-veshet” + “displaced gargeret.” The baraita gives three rulings — all of which presuppose that the slaughtered siman is the veshet. Why doesn’t the baraita ever discuss the reverse case (slaughter the gargeret, then the veshet is displaced)? Apparently because only veshet-slaughter is valid. This supports Rav Adda. The Gemara also extracts a crucial general rule from the safek-case: kol safek bi-shechita pesula — any doubt about the validity of shechita renders it pasul.
Key Terms:
- נִשְׁמְטָה (nishmeta) = Was displaced / dislodged — slipped from its anatomical position; a tereifa-status.
- כֹּל סָפֵק בִּשְׁחִיטָה פְּסוּלָה (kol safek bi-shechita pesula) = “Any doubt in slaughter renders it invalid” — a foundational principle.
Segment 9
TYPE: תירוץ
The Gemara rebuts the shachat challenge: the baraita features the gargeret being displaced because that siman is prone to displacement — not because veshet is the only valid cut.
Hebrew/Aramaic:
מִשּׁוּם דְּגַרְגֶּרֶת עֲבִידָא לְאִישְׁתְּמוֹטֵי.
English Translation:
The Gemara rejects that proof: The baraita mentions only the cutting of the gullet and displacement of the windpipe not because slaughter may be performed only by cutting the gullet. Rather, those scenarios were mentioned because the windpipe, unlike the gullet, is likely to be displaced.
קלאוד על הדף:
A simple anatomical/pedagogical answer: the windpipe is structurally prone to dislodgement (cartilaginous rings, looser attachment) while the gullet sits more firmly anchored. The baraita’s narrative therefore naturally features veshet-cutting paired with gargeret-displacement — it’s the realistic combination. The baraita is not implicitly excluding gargeret-slaughter; it just picks the case that happens. The challenge does not bind Rav Nachman.
Key Terms:
- עֲבִידָא לְאִישְׁתְּמוֹטֵי (avida le-ishtemutei) = “Prone to being displaced” — a Talmudic idiom for an anatomical tendency that frames pedagogical examples.
Segment 10
TYPE: תא שמע — קושיא ותירוץ
Second challenge (chatza’in): R’ Yehuda’s baraita says “veshet and veridin” — implying veshet is the unique necessary cut. The Gemara answers: veshet is mentioned only because of its adjacency to the veridin.
Hebrew/Aramaic:
תָּא שְׁמַע: שָׁחַט שְׁנֵי חֲצָאֵי סִימָנִין בְּעוֹף – פְּסוּלָה, וְאֵין צָרִיךְ לוֹמַר בִּבְהֵמָה. רַבִּי יְהוּדָה אוֹמֵר: בָּעוֹף – עַד שֶׁיִּשְׁחוֹט אֶת הַוֶּושֶׁט וְאֶת הַוְּרִידִין, מִשּׁוּם דְּוֶשֶׁט סָמוּךְ לִוְרִידִין.
English Translation:
The Gemara suggests: Come and hear a proof contrary to the opinion of Rav Naḥman from a baraita. If one cut two halves, one half of each of the simanim, in a bird, the slaughter is not valid, as the requirement is that a majority of one siman is cut; and needless to say the slaughter performed in that manner is not valid in the case of an animal, where the requirement is that a majority of both simanim are cut. Rabbi Yehuda says: In a bird the slaughter is not valid until he cuts the gullet and the veins; the veins must be cut so that the blood will drain from the body. The fact that Rabbi Yehuda mentions cutting only the gullet and not the windpipe indicates that slaughter is valid only when the gullet is cut. The Gemara rejects that proof: Rabbi Yehuda mentions only the gullet because the gullet is adjacent to the veins.
קלאוד על הדף:
The chatza’in challenge: a baraita about cutting “two half-simanim” first rules them pasul, then quotes R’ Yehuda’s add-on requirement: “veshet and veridin.” The challenge: R’ Yehuda specifies veshet — never gargeret + veridin. Apparently veshet is uniquely required. The Gemara’s answer is anatomical: R’ Yehuda mentions veshet not because only veshet validates the shechita but because veshet sits next to the veridin — and R’ Yehuda’s actual concern is the blood-draining via the veridin. He’s not making a statement about which siman is privileged; he’s referring to where the veridin are.
Key Terms:
- שְׁנֵי חֲצָאֵי סִימָנִין (shenei chatza’ei simanin) = Two half-simanim — half of the kaneh and half of the veshet, with neither siman reaching rov.
- סָמוּךְ (samuch) = Adjacent to — the veshet runs alongside the veridin, hence its mention by R’ Yehuda.
Segment 11
TYPE: תא שמע — ראייה לרב נחמן
Third challenge (gargeret) — this time in Rav Nachman’s favor: a baraita allows completing a half-cut gargeret after a long pause. If gargeret-cutting validates bird-shechita, Rav Nachman wins. The Gemara reassigns the case to behema.
Hebrew/Aramaic:
תָּא שְׁמַע: שָׁחַט חֲצִי גַרְגֶּרֶת, וְשָׁהָה כְּדֵי שְׁחִיטָה אַחֶרֶת, וְגָמַר שְׁחִיטָתוֹ – כְּשֵׁרָה. מַאי לָאו בְּעוֹף, וּמַאי גְּמָרָהּ – גְּמָרָהּ לְגַרְגֶּרֶת? לָא, בִּבְהֵמָה, וּמַאי גְּמָרָהּ – גְּמָרָהּ לִשְׁחִיטָה כּוּלַּהּ.
English Translation:
The Gemara suggests: Come and hear proof in support of the opinion of Rav Naḥman from a baraita. If one cut half the windpipe and interrupted the slaughter for an interval equivalent to the duration of the slaughter of another animal, and then completed his slaughter, the slaughter is valid and it is not invalidated due to an interrupted slaughter. What, is the baraita not referring to the slaughter of a bird? And what does the term: Completed it, mean in the baraita? Doesn’t it mean that he completed cutting the windpipe, which he had started cutting, indicating that with the cutting of the windpipe the slaughter is valid, in accordance with the opinion of Rav Naḥman as opposed to the opinion of Rav Adda bar Ahava? The Gemara rejects that proof: No, the baraita is referring to slaughter of an animal, for which both simanim must be cut. And what does the term: Completed it, mean in the baraita? It means that he completed the entire slaughter.
קלאוד על הדף:
The gargeret item. The baraita: someone cut half the windpipe, paused for a full kedei shechita acheret interval (which would normally invalidate shechita as sh’hiya), then “completed it” — and the shechita is valid. The challenge: this must be about a bird (where kaneh alone would suffice), and “completed it” must mean “finished cutting the windpipe” — meaning kaneh-shechita is valid, supporting Rav Nachman. The Gemara’s escape: the baraita is about behema, and “gemarah” means “completed the entire shechita” (cut both simanim). Why isn’t the sh’hiya disqualifying? Presumably because pre-rov cutting of kaneh isn’t yet “shechita” — the sh’hiya clock hasn’t started.
Key Terms:
- שָׁהָה כְּדֵי שְׁחִיטָה אַחֶרֶת (shaha kedei shechita acheret) = “Paused enough time for another slaughter” — the standard threshold for disqualifying sh’hiya.
- גְּמָרָהּ (gemarah) = “Completed it” — ambiguous between “finished the kaneh” (Rav Nachman reads) and “completed the whole shechita” (Gemara’s escape).
Segment 12
TYPE: תא שמע — ראייה לרב נחמן
Fourth challenge (pegima): a baraita about a pre-existing half-cut windpipe completed by any additional incision. Looks like proof for Rav Nachman; the Gemara reads it as behema-only.
Hebrew/Aramaic:
תָּא שְׁמַע: הֲרֵי שֶׁהָיָה חֲצִי קָנֶה פָּגוּם, וְהוֹסִיף עָלָיו כׇּל שֶׁהוּא וּגְמָרוֹ – שְׁחִיטָתוֹ כְּשֵׁרָה. מַאי לָאו בְּעוֹף, וּמַאי גְּמָרוֹ – גְּמָרוֹ לְקָנֶה? לָא, בִּבְהֵמָה, וּמַאי גְּמָרוֹ – גְּמָרוֹ לְוֶושֶׁט.
English Translation:
The Gemara suggests: Come and hear proof in support of the opinion of Rav Naḥman from a baraita: In a case where half of the windpipe was deficient, i.e., somewhat cut, prior to the slaughter and the slaughterer added to that deficiency an incision of any size, and completed it, his slaughter is valid. What, is it not referring to the slaughter of a bird? And what does the term: Completed it, mean in the baraita? Doesn’t it mean that he completed cutting the majority of the windpipe, indicating that cutting the windpipe renders the bird fit for consumption? The Gemara rejects that proof: No, the baraita is referring to slaughter of an animal, for which both simanim must be cut. And what does the term: Completed it, mean in the baraita? It means that he completed the entire slaughter by cutting the gullet.
קלאוד על הדף:
The pegima item. The baraita: a kaneh was already half-cut before the slaughter began (a pre-existing notch), the shochet added even the slightest cut, and “completed it” — and the shechita is valid. Same reading-pattern: the challenge wants this to be a bird (the smallest possible addition validates kaneh-rov = bird-shechita), supporting Rav Nachman. The Gemara escapes again by reassigning to behema and reading “gemaro” as completing the whole shechita (i.e., also cutting the veshet). Same answer-template as Segment 11.
Key Terms:
- פָּגוּם (pagum) = Deficient — already notched / partially cut.
- כׇּל שֶׁהוּא (kol shehu) = “Any amount” — even a hair’s breadth of additional cutting.
Segment 13
TYPE: תא שמע — תיובתא
Fifth challenge (chatat ha-of): a baraita on the priestly procedure for a bird sin-offering uses “veshet or kaneh” — explicit either/or. The Gemara declares this a conclusive tiyuvta against Rav Adda.
Hebrew/Aramaic:
תָּא שְׁמַע: כֵּיצַד מוֹלְקִין חַטַּאת הָעוֹף? חוֹתֵךְ שִׁדְרָה וּמַפְרֶקֶת בְּלֹא רוֹב בָּשָׂר עַד שֶׁמַּגִּיעַ לַוֶּושֶׁט אוֹ לַקָּנֶה; הִגִּיעַ לַוֶּושֶׁט אוֹ לַקָּנֶה – חוֹתֵךְ סִימָן אֶחָד וְרוֹב בָּשָׂר עִמּוֹ, וּבָעוֹלָה – שְׁנַיִם אוֹ רוֹב שְׁנַיִם. תְּיוּבְתָּא דְּרַב אַדָּא בַּר אַהֲבָה, תְּיוּבְתָּא.
English Translation:
The Gemara suggests: Come and hear proof in support of the opinion of Rav Naḥman from a baraita: How does one pinch the nape of the neck of a bird sin offering? Using his thumbnail, the priest cuts the spine and the neck bone, without cutting through the majority of the surrounding flesh until he reaches either the gullet or the windpipe. Once he reaches the gullet or the windpipe, he cuts one siman with his nail and a majority of the surrounding flesh with it. And in the case of a bird burnt offering, he cuts the two simanim or the majority of the two simanim. The Gemara concludes: The refutation of the opinion of Rav Adda bar Ahava from this baraita is indeed a conclusive refutation.
קלאוד על הדף:
The decisive chatat ha-of item. The baraita describes melika of a chatat ha-of: the priest cuts down through spine and mafreket until he reaches veshet or kaneh — and at that point cuts one siman plus a rov of the surrounding flesh. For an olah ha-of, both simanim or rov of both. The baraita’s repeated phrase “veshet or kaneh” is a smoking gun: melika is valid via either. Since melika for a chatat ha-of is the priestly bird-shechita analogue (one siman, like ordinary bird-shechita), this proves either siman validates bird-shechita. The Gemara pronounces formally: tiyuvta de-Rav Adda bar Ahava, tiyuvta — a conclusive refutation.
Key Terms:
- תְּיוּבְתָּא (tiyuvta) = “Conclusive refutation” — the Talmud’s strongest term for an unanswerable objection.
- רוֹב בָּשָׂר (rov basar) = Majority of the surrounding flesh — distinct from rov of the siman; here meaning the flesh-volume cut with the siman.
- עוֹלָה (olah) [ha-of] = Bird burnt-offering — requires two simanim cut (or rov of two), unlike the chatat ha-of.
Segment 14
TYPE: שאלה ודחייה
The Gemara revisits the supposedly-conclusive tiyuvta: maybe melika is different from regular shechita (since the spine and mafreket are already cut), so the chatat-ha-of evidence may not transfer to ordinary chullin-bird-shechita.
Hebrew/Aramaic:
מַאי הָוֵי עֲלַהּ? מַאי הָוֵי עֲלַהּ?! כִּדְקָאָמְרַתְּ, דִּלְמָא שָׁאנֵי הָתָם, דְּאִיכָּא שִׁדְרָה וּמַפְרֶקֶת.
English Translation:
The Gemara asks: What halakhic conclusion was reached about the matter? The Gemara asks in response: What halakhic conclusion was reached about the matter? It is as you said, that the opinion of Rav Adda bar Ahava was conclusively refuted. The Gemara says that there is not absolute proof from the baraita, as perhaps it is different there with regard to pinching, as in that case there is the spine and the neck bone that are cut initially, and therefore cutting the windpipe is sufficient. But in the case of slaughter of a non-sacred bird, perhaps only if one cuts the gullet the slaughter is valid.
קלאוד על הדף:
A meta-question: with Rav Adda already nominally refuted, what’s the actual halakhic psak? The Gemara hedges: perhaps melika is structurally different — there the spine and mafreket are already severed, and only then the kohen turns to the simanim. With so much already cut, kaneh-alone may suffice for melika but not necessarily for ordinary chullin-shechita. So Rav Adda may still hold for chullin-shechita even though the chatat-ha-of baraita supports Rav Nachman on its face. The status quo of the machloket is unresolved.
Key Terms:
- מַאי הָוֵי עֲלַהּ (mai havei alah) = “What is the conclusion?” — a Talmudic formula asking for the practical halakhic outcome.
- שָׁאנֵי הָתָם (sha’ani hatam) = “It is different there” — a Talmudic distinction-marker that limits the scope of an apparent proof.

A famous practical case: a duck arrived at Rava’s house with blood on its neck — was its gullet perforated (tereifa) or its windpipe nicked? Rava asks: what should we do?
Hebrew/Aramaic:
מַאי? תָּא שְׁמַע: דְּהָהוּא בַּר אֲוָוזָא דַּהֲוָה בֵּי רָבָא, אֲתָא כִּי מְמַסְמַס קוֹעֵיהּ דְּמָא. אָמַר רָבָא: הֵיכִי נַעֲבֵיד?
English Translation:
The Gemara asks: What then is the halakha in the case of slaughter? The Gemara answers: Come and hear proof from the following incident, that there was a certain duck that was in the house of Rava, which came for slaughter with its neck filthy with blood and they did not know whether the blood was the result of its windpipe having been severed or its gullet having been perforated, in which cases the duck is a tereifa. Rava said: What should we do with regard to this duck?
קלאוד על הדף:
A pivot from theoretical machloket to a real-life ma’aseh rav. A duck (bar avoza) showed up at Rava’s house with its neck smeared bloody (memasmes ko’ei dama) — and they didn’t know whether the bleeding came from (1) a nick on the kaneh (no halakhic problem — the duck is still kosher) or (2) a puncture in the veshet (a tereifa — neikuv ha-veshet). Rava asks his disciples how to proceed. The case is structurally perfect for the machloket because resolving it requires knowing whether kaneh-shechita can validate. The amud ends with Rava’s question — the resolution comes on 28b.
Key Terms:
- בַּר אֲוָוזָא (bar avoza) = Duck — a domesticated bird.
- מְמַסְמַס קוֹעֵיהּ דְּמָא (memasmes ko’ei dama) = “Its neck smeared with blood” — a vivid Aramaic phrase describing the visible blood on the bird’s neck.
- נֶקֶב הַוֶּושֶׁט (nekev ha-veshet) = Perforation of the gullet — a tereifa-status (the veshet must be intact for kosher consumption).
Amud Bet (28b)
Segment 1
TYPE: התלבטות
Rava’s deliberation continues — both straightforward approaches fail: slaughter-first-examine-later risks slaughtering on the perforation; examine-first-slaughter-later doesn’t work because (per Rabba) the veshet can’t be examined from the outside.
Hebrew/Aramaic:
נִשְׁחֲטֵיהּ וַהֲדַר נִבְדְּקֵיהּ? דִּלְמָא בִּמְקוֹם נֶקֶב קָשָׁחֵיט! נִבְדְּקֵיהּ וַהֲדַר נִשְׁחֲטֵיהּ? הָאָמַר רַבָּה: וֶושֶׁט אֵין לוֹ בְּדִיקָה מִבַּחוּץ אֶלָּא מִבִּפְנִים!
English Translation:
If one suggests: Let us slaughter it and then we will examine it to determine whether its windpipe was severed or its gullet was perforated, that is difficult, because perhaps the slaughterer will slaughter the duck precisely in the place of the perforation and it will be impossible to determine whether the gullet was perforated before the slaughter. If one suggests: Let us slice open the hide and examine the simanim and then we will slaughter it, that is difficult, because didn’t Rabba say: The gullet has no possible examination from without, as its outer side is red, and a small perforation would be indiscernible, but only from within, as its inner side is white, and blood at the site of the perforation would be discerned?
קלאוד על הדף:
Rava’s bind. Option 1: shecht first, then examine — but a perforation in the veshet could end up coinciding with the shechita-cut, leaving no way to determine whether the perforation pre-dated the shechita. Option 2: examine first, then shecht — but Rabba’s principle: the veshet cannot be examined externally (its outer side is red, masking any small perforation in blood-tone) — only internally (the inner side is white, where a perforated spot would show blood clearly). So the bird can’t be examined while alive. Both approaches fail; an alternative is needed.
Key Terms:
- בְּדִיקָה (bedika) = Examination — the rabbinic procedure of inspecting an animal for tereifa-status post-slaughter.
- רַבָּה (Rabba) = The Babylonian Amora — uncle of Rava, source of the principle that the veshet is examined only from within.
- מִבִּפְנִים (mi-bifnim) = “From within / the inside” — the white inner side of the veshet, where a perforation would show blood.
Segment 2
TYPE: פתרון רב יוסף בריה דרבא
Rav Yosef, Rava’s son, devises an elegant three-step solution that resolves the dilemma — and demonstrates that the mishna’s “one siman” really does mean either one (validating Rav Nachman).
Hebrew/Aramaic:
אֲמַר לֵיהּ רַב יוֹסֵף בְּרֵיהּ: נִבְדְּקֵיהּ לְקָנֶה, וְנִשְׁחֲטֵיהּ לְקָנֶה וְלַכְשְׁרֵיהּ, וַהֲדַר לֵפְכֵוהּ לְוֶשֶׁט וְלִבְדְּקֵיהּ. אָמַר רָבָא: חַכִּים יוֹסֵף בְּרִי בִּטְרֵפוֹת כְּרַבִּי יוֹחָנָן. אַלְמָא אֶחָד דְּקָאָמַר – אוֹ הַאי אוֹ הַאי.
English Translation:
Rav Yosef, son of Rava, said to him: Let us examine the windpipe, as it is possible to discern from without whether the majority of the windpipe was severed, and then cut the duck’s windpipe and thereby render it permitted, as cutting either of the two simanim suffices in a bird. And then let us turn the gullet inside out and examine its inner side to determine whether it was perforated and the duck is a tereifa. Rava said: My son Yosef is as wise in the halakhot of tereifot as Rabbi Yoḥanan. Apparently, one siman, which is taught in the mishna as being sufficient in the slaughter of a bird, means either this siman, the gullet, or that siman, the windpipe.
קלאוד על הדף:
Rav Yosef bar Rava’s brilliant three-step solution: (1) Examine the kaneh externally — the trachea can be inspected from without (unlike the veshet); confirm it’s intact. (2) Slaughter the kaneh — bird-shechita is valid via the kaneh alone (per Rav Nachman). (3) Turn the veshet inside-out and examine it from within — now legitimate because the bird is already dead and rendered kosher by the kaneh-shechita. If the veshet is found perforated, the duck is tereifa; otherwise kosher. Rava’s praise: “My son Yosef is as wise in tereifot as Rabbi Yochanan.” The Gemara’s payoff: this entire solution presupposes that bird-shechita via the kaneh validates — proving Rav Nachman. Echad in the mishna means either one — Rav Nachman wins the machloket.
Key Terms:
- חַכִּים יוֹסֵף בְּרִי בִּטְרֵפוֹת כְּרַבִּי יוֹחָנָן (chakim Yosef beri be-tereifot ke-Rabbi Yochanan) = “Yosef my son is as wise in tereifot as Rabbi Yochanan” — Rava’s praise; a high compliment.
- לֵפְכֵוהּ (lefkhevhu) = “Let us turn it inside-out” — the procedural step of inverting the veshet to inspect its white inner side.
- אֶחָד דְּקָאָמַר אוֹ הַאי אוֹ הַאי (echad de-ka’amar — o hai o hai) = “The ‘echad’ [of the mishna] means: either this or that” — the conclusive ruling against Rav Adda.

TYPE: דעת רב חסדא — הסבר רבי יהודה
A new sub-sugya on R’ Yehuda’s veridin-rule. Rav Chisda restricts it to birds (roasted whole) — animals (quartered into limbs) don’t need the veridin cut.
Hebrew/Aramaic:
רַבִּי יְהוּדָה אוֹמֵר: עַד שֶׁיִּשְׁחוֹט. אָמַר רַב חִסְדָּא: לֹא אָמַר רַבִּי יְהוּדָה אֶלָּא בְּעוֹף, הוֹאִיל וְצוֹלֵהוּ כּוּלּוֹ כְּאֶחָד, אֲבָל בְּהֵמָה, כֵּיוָן דִּמְנַתְּחַהּ אֵבֶר אֵבֶר – לָא צְרִיךְ.
English Translation:
§ The mishna states: Rabbi Yehuda says: The slaughter is not valid until he cuts the veins in the neck. Rav Ḥisda said: Rav Yehuda said that one must cut the veins only in the slaughter of a bird, as one typically roasts it in its entirety as one whole entity; therefore, one must cut the veins to ensure that the blood drains. But with regard to the slaughter of an animal, since it is typically quartered into limbs, resulting in the blood draining more readily, one need not cut the veins.
קלאוד על הדף:
The Gemara turns to the second half of the mishna — R’ Yehuda’s add-on requirement that the veridin (jugulars) be cut. Rav Chisda offers a key narrowing: R’ Yehuda’s requirement applies only to birds, not animals. The reason is culinary-anatomical: birds are typically roasted whole, so blood retained in the body becomes a problem (the blood would coagulate and forbid consumption); animals are quartered limb-by-limb (menatcha ever ever), which provides natural blood-drainage and obviates the need to puncture veridin during slaughter. The next segments will probe whether R’ Yehuda’s veridin-cut is technically part of shechita or merely a post-shechita auxiliary act.
Key Terms:
- רַב חִסְדָּא (Rav Chisda) = An early Babylonian Amora; a major voice in tereifot-halakha.
- צוֹלֵהוּ כּוּלּוֹ כְּאֶחָד (tzolehu kulo ke-echad) = “Roasts it whole as one” — birds were typically roasted whole on a spit.
- מְנַתְּחַהּ אֵבֶר אֵבֶר (menatcha ever ever) = “Quarters it limb-by-limb” — animals were butchered into pieces before cooking.
Segment 4
TYPE: קושיא על רב חסדא
If R’ Yehuda’s veridin-requirement is merely about blood-drainage (as Rav Chisda implies), why does the mishna use the verb “yishchot” (slaughter) — suggesting the veridin-cut is part of the shechita itself?
Hebrew/Aramaic:
לְמֵימְרָא דְּטַעְמָא דְּרַבִּי יְהוּדָה מִשּׁוּם דָּם הוּא? וְהָתְנַן: רַבִּי יְהוּדָה אוֹמֵר: עַד שֶׁיִּשְׁחוֹט אֶת הַוְּורִידִין.
English Translation:
The Gemara asks: Is that to say that the reason that Rabbi Yehuda requires cutting of the veins is due to the need to drain the blood? But didn’t we learn in the mishna: Rabbi Yehuda says: The slaughter is not valid until he cuts [sheyishḥot] the veins, indicating that the cutting of the veins is a component of the slaughter [sheḥita]?
קלאוד על הדף:
The Gemara challenges Rav Chisda’s framing. The mishna’s verb is “ad she-yishchot” — “until he slaughters the veridin.” The verb yishchot (the precise shechita-verb) implies that the veridin-cut is itself a component of shechita — not merely a drainage-procedure. If Rav Chisda were right (the veridin-rule is about blood), the mishna should have used a different verb like “until he punctures” them. The use of shachat suggests the veridin-cut is technically part of the shechita-procedure itself. The next segment will offer a way to reread the mishna’s verb.
Key Terms:
- טַעְמָא (ta’ama) = Reason / rationale — the underlying motive for a halakha.
- שְׁחִיטָה (shechita) = The technical Torah-act of ritual slaughter — distinct from mere blood-puncturing.
Segment 5
TYPE: תירוץ
Reread the mishna: “yishchot” actually means “punctures at the time of shechita.” The veridin-cut is not part of shechita but a simultaneous blood-puncturing.
Hebrew/Aramaic:
אֵימָא עַד שֶׁיְּנַקֵּב אֶת הַוְּורִידִין, וּמַאי ״עַד שֶׁיִּשְׁחוֹט״? עַד שֶׁיִּנְקוֹב בִּשְׁעַת שְׁחִיטָה.
English Translation:
The Gemara answers: Say that Rabbi Yehuda’s statement is until he punctures the veins. And what is the meaning of: Until he cuts? Until he punctures the veins at the moment of slaughter, when the blood flows.
קלאוד על הדף:
The Gemara rescues Rav Chisda by re-reading the mishna: “ad she-yishchot” doesn’t mean “until he performs the shechita-action on the veridin”; rather it means “until he punctures them at the time of shechita.” The verb expresses timing, not technique. The veridin must be punctured during the shechita-window (because at that moment the blood is still warm and flows readily out, as Segment 8 will explain) — but the act of puncturing them is technically not part of the shechita itself.
Key Terms:
- בִּשְׁעַת שְׁחִיטָה (bi-she’at shechita) = “At the time of shechita” — the temporal window during which the veridin must be punctured.
- יְּנַקֵּב (yenakev) = Punctures — distinct from yishchot (slaughters); the Gemara argues this is the real meaning of the mishna’s word.
Segment 6
TYPE: תא שמע ותירוץ
A baraita says “veridin bi-shechita” (the veridin via shechita) — apparently treating them as part of shechita. The Gemara re-reads it the same way: “must be punctured at the time of shechita.”
Hebrew/Aramaic:
תָּא שְׁמַע: וְורִידִין בִּשְׁחִיטָה, דִּבְרֵי רַבִּי יְהוּדָה. אֵימָא: וְורִידִין צָרִיךְ לְנַקְּבָן בִּשְׁעַת שְׁחִיטָה, דִּבְרֵי רַבִּי יְהוּדָה.
English Translation:
The Gemara suggests: Come and hear proof rejecting this interpretation of Rabbi Yehuda’s statement from a baraita: The veins through slaughter, this is the statement of Rabbi Yehuda, which indicates that the cutting of the veins is a component of slaughter. The Gemara rejects that proof: Say that the correct reading of the baraita is: He must puncture the veins at the moment of slaughter; this is the statement of Rabbi Yehuda.
קלאוד על הדף:
A more pointed challenge: a baraita straight up says “veridin bi-shechita” — “the veridin through/in shechita.” This phrasing more strongly suggests the veridin are part of the shechita itself. The Gemara applies the same re-reading: read “bi-shechita” as “at the time of shechita” (temporal preposition), not “as part of shechita.” The pattern: any Tannaitic statement linking veridin to shechita is parsed as a temporal connection rather than a structural one.
Key Terms:
- וְורִידִין בִּשְׁחִיטָה (veridin bi-shechita) = The contested phrase — the bet preposition is ambiguous between “as part of” and “at the time of.”
Segment 7
TYPE: תא שמע — קושיא מהוויכוח
Strongest challenge yet: a baraita where the Rabbis explicitly ask R’ Yehuda why he insists the cut be “during shechita” — implying R’ Yehuda does hold it must be at that time.
Hebrew/Aramaic:
תָּא שְׁמַע: אָמְרוּ לוֹ לְרַבִּי יְהוּדָה, מֵאַחַר שֶׁלֹּא הוּזְכְּרוּ וְורִידִין אֶלָּא לְהוֹצִיא מֵהֶן דָּם, מָה לִי בִּשְׁחִיטָה, מָה לִי שֶׁלֹּא בִּשְׁחִיטָה? מִכְּלָל דְּרַבִּי יְהוּדָה סָבַר בִּשְׁחִיטָה.
English Translation:
The Gemara suggests: Come and hear another proof from a baraita: The Rabbis said to Rabbi Yehuda: Since veins were mentioned only to drain blood from them, what difference is there to me whether one cuts them as a component of slaughter, and what difference is there to me whether one cuts them not as a component of slaughter? One can learn by inference from this baraita that Rabbi Yehuda holds that one cuts the veins as a component of slaughter.
קלאוד על הדף:
The Rabbis (anonymous interlocutors) press R’ Yehuda in a baraita: “Since the only purpose of mentioning veridin is blood-drainage, why does it matter whether you cut them as part of shechita or not?” The inference: R’ Yehuda must hold that the cut is as part of shechita — otherwise their question makes no sense. The implication challenges Rav Chisda’s reading: R’ Yehuda apparently does treat the veridin-cut as structurally part of shechita, not just temporally aligned with it.
Key Terms:
- לְהוֹצִיא מֵהֶן דָּם (le-hotzi mehen dam) = “To drain the blood from them” — the Rabbis’ framing of the only purpose of mentioning veridin.
- מָה לִי … מָה לִי (mah li … mah li) = “What difference does it make to me whether… or whether…” — a Talmudic rhetorical formula for indifference between options.
Segment 8
TYPE: תירוץ — הסבר חם וקר
The Gemara rescues Rav Chisda: the Rabbis are asking why specifically at the moment of shechita — and R’ Yehuda’s answer is physiological: warm blood flows freely, cool blood doesn’t.
Hebrew/Aramaic:
הָכִי קָאָמְרִי לַהּ: מָה לִי לְנַקְּבָן בִּשְׁעַת שְׁחִיטָה, מָה לִי לְנַקְּבָן שֶׁלֹּא בִּשְׁעַת שְׁחִיטָה? וְהוּא סָבַר: בִּשְׁעַת שְׁחִיטָה אָתֵי דָּם דְּחָיֵים, שֶׁלֹּא בִּשְׁעַת שְׁחִיטָה לָא אָתֵי דָּם דְּקָרִיר.
English Translation:
The Gemara rejects this proof. This is what the Rabbis are saying to Rabbi Yehuda: What difference is there to me whether one punctures them at the moment of slaughter, and what difference is there to me whether one punctures them not at the moment of slaughter? One can puncture the veins after the slaughter. And Rabbi Yehuda holds that at the time of slaughter the blood emerges from the body quickly because the blood is warm; when it is not at the time of slaughter, the blood does not emerge from the body quickly because it is cool.
קלאוד על הדף:
A careful re-reading of the Rabbis’ challenge: their question is not “why must it be part of shechita?” but “why must it be at the time of shechita?” — they wonder why R’ Yehuda insists on the temporal link. R’ Yehuda’s answer (filled in by the Gemara): warm blood flows; cool blood doesn’t. At the moment of shechita, the blood is still warm and gushes out through the punctured veridin; after shechita, the blood cools and stops flowing. This vivid physiological reasoning preserves Rav Chisda’s reading: the veridin-cut is timed to coincide with shechita for purely drainage reasons.
Key Terms:
- דָּם דְּחָיֵים (dam de-chayyim) = Warm/lively blood — flows freely.
- דָּם דְּקָרִיר (dam de-karir) = Cool blood — slow-moving / clotting; the post-mortem state.
Segment 9
TYPE: בעיא דרבי ירמיה
R’ Yirmeya raises a follow-up dilemma: do the shechita-disqualifications (sh’hiya, derasa) apply when cutting the veridin too?
Hebrew/Aramaic:
בָּעֵי רַבִּי יִרְמְיָה: וְורִידִין לְרַבִּי יְהוּדָה, שָׁהָה בָּהֶן, דָּרַס בָּהֶן, מַהוּ?
English Translation:
Rabbi Yirmeya raises a dilemma: In cutting the veins according to Rabbi Yehuda, if one interrupted the act in the midst of cutting them, or if he pressed the knife and cut them instead of drawing the knife back and forth, what is the halakha? Do these actions, which invalidate slaughter when cutting the simanim, also invalidate slaughter when performed in the cutting of the veins?
קלאוד על הדף:
R’ Yirmeya tests the boundary: if R’ Yehuda thinks veridin-cutting is part of shechita, then sh’hiya (interrupting) and derasa (pressing) — disqualifications of shechita — should apply to veridin-cutting too. If R’ Yehuda thinks it’s a separate drainage-act, the disqualifications don’t apply. This be’aya is essentially asking which side of the Rav Chisda / opposing-baraita dispute is correct. The next segment delivers the answer.
Key Terms:
- רַבִּי יִרְמְיָה (Rabbi Yirmeya) = An Eretz-Yisrael Amora known for raising sharp boundary-case dilemmas.
- בָּעֵי (ba’ei) = “Raises an inquiry / asks” — formula for posing a halakhic be’aya.
Segment 10
TYPE: תשובת רבי יוחנן
An anonymous elder transmits R’ Yochanan’s answer (via R’ Elazar): the veridin can be punctured even with a thorn — they don’t require a shechita-knife or technique.
Hebrew/Aramaic:
אֲמַר לֵיהּ הָהוּא סָבָא: הָכִי אָמַר רַבִּי אֶלְעָזָר, וְאָמְרִי לַהּ: אֲמַר לֵיהּ הָהוּא סָבָא לְרַבִּי אֶלְעָזָר, הָכִי אָמַר רַבִּי יוֹחָנָן: מְנַקְּבָן בְּקוֹץ וְהֵן כְּשֵׁרִין.
English Translation:
A certain elder said to him: This is what Rabbi Elazar said; and some say that a certain elder said to Rabbi Elazar that this is what Rabbi Yoḥanan said: He punctures the veins with a thorn and their cutting is valid. Cutting the veins is not a component of the slaughter.
קלאוד על הדף:
A decisive answer: R’ Yochanan rules that the veridin may be punctured with a thorn (kotz) — any sharp object — and the puncture is valid. The implication is crystal clear: cutting the veridin is not part of shechita (which requires a kosher knife and proper drawing technique). The veridin-cut is purely a drainage-action. This confirms Rav Chisda’s position. Sh’hiya and derasa do not apply.
Key Terms:
- קוֹץ (kotz) = Thorn — a non-knife sharp object; the fact that R’ Yochanan permits its use proves the veridin-cut is not shechita.
- הָהוּא סָבָא (hahu sava) = “A certain elder” — an anonymous transmitter, a common Talmudic figure.
Segment 11
TYPE: ברייתא תומכת ברב חסדא
A baraita is brought “tanya ke-vateih de-Rav Chisda” — explicitly supporting Rav Chisda’s reading: R’ Yehuda’s veridin-requirement is only for birds, not animals.
Hebrew/Aramaic:
תַּנְיָא כְּוָותֵיהּ דְּרַב חִסְדָּא: שָׁחַט שְׁנֵי חֲצָאֵי סִימָנִין בְּעוֹף – פָּסוּל, וְאֵין צָרִיךְ לוֹמַר בִּבְהֵמָה. רַבִּי יְהוּדָה אוֹמֵר: בְּעוֹף – עַד שֶׁיִּשְׁחוֹט אֶת הַוֶּושֶׁט וְאֶת הַוְּורִידִין.
English Translation:
The Gemara notes that it is taught in a baraita in accordance with the opinion of Rav Ḥisda that Rabbi Yehuda requires cutting of the veins only in the slaughter of birds, and not in the slaughter of animals. If one cut two halves, one half of each of the simanim, in a bird, the slaughter is not valid, and needless to say the slaughter performed in that manner is not valid in the case of an animal. Rabbi Yehuda says: In a bird the slaughter is not valid until he cuts the gullet and the veins.
קלאוד על הדף:
Decisive Tannaitic backing for Rav Chisda: this baraita explicitly limits R’ Yehuda’s veridin-rule to bird slaughter (“ba-of — until he cuts the veshet and the veridin”). The construction “tanya ke-vateih” (“a baraita is taught in accordance with him”) is a Talmudic seal-of-approval — Rav Chisda’s reading is shown to have authoritative pre-existing Tannaitic support. The combination of R’ Yochanan’s thorn-ruling (Segment 10) and this baraita closes the veridin-sugya in Rav Chisda’s favor: veridin-cutting is bird-only, drainage-purposed, not part of shechita.

TYPE: מחלוקת אמוראים — מחצה על מחצה
The third sub-sugya. The mishna ruled “half-a-siman in a bird is pasul”; the amoraim now dispute the conceptual question: does exactly half count as the required rov, or not?
Hebrew/Aramaic:
חֲצִי אֶחָד בְּעוֹף וְכוּ׳. אִתְּמַר: רַב אָמַר: מֶחֱצָה עַל מֶחֱצָה כְּרוֹב, רַב כָּהֲנָא אָמַר: מֶחֱצָה עַל מֶחֱצָה אֵינוֹ כְּרוֹב.
English Translation:
§ The mishna teaches: If one cut half of one siman in a bird or one and a half simanim in an animal, his slaughter is not valid. It was stated that there is an amoraic dispute. Rav said: The halakhic status of a siman of which precisely half was cut and half remained uncut is like that of a siman of which the majority was cut. Rav Kahana said: The halakhic status of a siman of which precisely half was cut and half remained uncut is not like that of a siman of which the majority was cut.

The Gemara now opens a deep conceptual machloket about the halakhic status of an exact half. The mishna ruled “chetzi echad ba-of pesula” — half a siman in a bird is invalid. Rav: nevertheless, conceptually mechetza al mechetza ke-rov — exactly half is equivalent to a majority (and the mishna is therefore a rabbinic stringency). Rav Kahana: mechetza al mechetza eino ke-rov — exactly half is not equivalent to a majority (and the mishna’s invalidation is intrinsic, biblical). This dispute reaches far beyond shechita — it’s a foundational rov-machetzit question with implications across halakha.
Key Terms:
- מֶחֱצָה עַל מֶחֱצָה (mechetza al mechetza) = “Half-to-half” — exactly equal halves with no majority either way.
- רוֹב (rov) = Majority — the threshold for halakhic effect in many contexts (shechita, mikva-water-volume, etc.).
Segment 13
TYPE: הסבר הסברות
The Gemara articulates the underlying conceptual difference: Rav reads Sinai’s command negatively (“do not leave a majority uncut”); Rav Kahana reads it positively (“cut the majority”).
Hebrew/Aramaic:
רַב אָמַר: מֶחֱצָה עַל מֶחֱצָה כְּרוֹב, הָכִי אֲמַר לֵיהּ רַחֲמָנָא לְמֹשֶׁה: ״לָא תְּשַׁיַּיר רוּבָּא״. רַב כָּהֲנָא אָמַר: מֶחֱצָה עַל מֶחֱצָה אֵינוֹ כְּרוֹב, הָכִי אֲמַר לֵיהּ רַחֲמָנָא לְמֹשֶׁה: ״שְׁחוֹט רוּבָּא״.
English Translation:
The Gemara elaborates. Rav said: The halakhic status of a siman of which precisely half was cut and half remained uncut is like that of a siman of which the majority was cut, and this is what the Merciful One said to Moses: Do not leave the majority uncut. When cutting precisely half, the majority does not remain uncut. Rav Kahana said: The halakhic status of a siman of which precisely half was cut and half remained uncut is not like that of a siman of which the majority was cut, and this is what the Merciful One said to Moses: Cut the majority of the siman. Therefore, cutting precisely half is insufficient.
קלאוד על הדף:
A beautiful framing of the dispute as two different reconstructions of God’s Sinai-command to Moshe. Rav: God said “lo teshayyer rubba” — “don’t leave a majority uncut.” With exactly half cut, exactly half remains — not a majority uncut. So half cut = the requirement met. Rav Kahana: God said “shechot rubba” — “cut a majority.” Exactly half is not a majority. So half cut = requirement not met. The difference is grammatical-affirmative vs. negative phrasing of the same command, but with opposite halakhic outcomes for the borderline 50/50 case. This is one of the classic rov-dialectics of Shas.
Key Terms:
- לָא תְּשַׁיַּיר רוּבָּא (lo teshayyer rubba) = “Do not leave a majority [uncut]” — Rav’s negative-phrasing reconstruction.
- שְׁחוֹט רוּבָּא (shechot rubba) = “Slaughter a majority” — Rav Kahana’s positive-phrasing reconstruction.
- רַחֲמָנָא (Rachamana) = “The Merciful One” — Talmudic designation for God as the Author of Torah.
Segment 14
TYPE: סִימָן
Mnemonic for the four upcoming proofs in the Rav / Rav Kahana dispute: chetzi, Ketina, gargeret, pegima.
Hebrew/Aramaic:
(סִימָן: חֲצִי, קַטִּינָא, גַּרְגֶּרֶת, פְּגִימָה).
English Translation:
The Gemara provides a mnemonic for the proofs that it cites with regard to this dispute: Half, Ketina, windpipe, deficiency.
קלאוד על הדף:
Another mnemonic preview — four proofs against Rav (i.e., supporting Rav Kahana that mechetza eino ke-rov). The four keywords correspond to: (1) chetzi — the mishna’s “chetzi echad ba-of pesula”; (2) Ketina — Rav Ketina’s proof from the broken pottery-vessel; (3) gargeret — the half-windpipe baraita; (4) pegima — the deficient-kaneh baraita. Only the first two will appear in this amud; the others continue on 29a.
Key Terms:
- קַטִּינָא (Ketina) = Rav Ketina — the Amora who brings the broken-vessel proof.
Segment 15
TYPE: קושיא ממשנתינו (חֲצִי)
The chetzi item. The mishna itself says “chetzi echad ba-of pesula” — if half-equals-majority, why is half pasul? The Gemara answers: pasul mi-derabbanan (rabbinic stringency).
Hebrew/Aramaic:
תְּנַן: חֲצִי אֶחָד בְּעוֹף, וְאֶחָד וַחֲצִי בַּבְּהֵמָה – שְׁחִיטָתוֹ פְּסוּלָה. אִי אָמְרַתְּ מֶחֱצָה עַל מֶחֱצָה כְּרוֹב, אַמַּאי פָּסוּל? הָא עֲבַד לֵיהּ רוֹב! מִדְּרַבָּנַן, דִּלְמָא לָא אָתֵי לְמֶעְבַּד פַּלְגָא.
English Translation:
We learned in the mishna: If one cut half of one siman in a bird or one and a half simanim in an animal, his slaughter is not valid. The Gemara questions the opinion of Rav: If you say that the halakhic status of a siman of which precisely half was cut and half remained uncut is like that of a siman of which the majority was cut, why is his slaughter not valid? By cutting half, didn’t he perform the cutting of a majority of the siman? The Gemara rejects that proof: By rabbinic law, the slaughter is not valid, due to the concern that perhaps he will not come to perform cutting on even half of the siman.
קלאוד על הדף:
The most obvious challenge: the mishna itself says “chetzi echad ba-of pesula” — if Rav holds half-equals-majority, why isn’t half kosher? Rav’s answer: the mishna’s pesul is mi-derabbanan, not d’oraita. Why did the Rabbis disqualify? Because if people thought “even half works,” some might come up short of half (a slight miscalibration) and call it kosher — so the Rabbis pushed the threshold up to a clear rov to leave margin. Rav can retain mechetza al mechetza ke-rov at the biblical level while accepting the rabbinic requirement of true rov.
Key Terms:
- תְּנַן (tenan) = “We learned [in our mishna]” — a Talmudic formula introducing a proof from the mishna at hand.
- דִּלְמָא לָא אָתֵי לְמֶעְבַּד פַּלְגָא (dilma la atei le-me’evad palga) = “Perhaps he will not even come to perform [a full] half” — the rabbinic safety-margin reasoning.
Segment 16
TYPE: תא שמע — קושיא מכלי חרס (קַטִּינָא)
Rav Ketina brings a powerful proof against Rav from the laws of pottery-tumah: if a tamei kli cheres breaks in halves that might be equal, both remain tamei — because it’s impossible to split exactly.
Hebrew/Aramaic:
אָמַר רַב קַטִּינָא, תָּא שְׁמַע: חֲלָקוֹ לִשְׁנַיִם וְהֵן שָׁוִין – שְׁנֵיהֶם טְמֵאִין, לְפִי שֶׁאִי אֶפְשָׁר לְצַמְצֵם.
English Translation:
Rav Ketina said: Come and hear proof contrary to Rav’s opinion from a baraita with regard to an impure earthenware vessel that is purified through being broken. If it is broken in two, the larger portion remains impure and the smaller portion is purified. If he divided it into two and they are seemingly equal halves, both are impure, because it is impossible to measure precisely in breaking an earthenware vessel and render both halves equal. Since it is impossible to determine which half is larger, both remain impure due to uncertainty.
קלאוד על הדף:
Background: an earthenware vessel (kli cheres) that became tamei is purified by being broken — the smaller shard becomes tahor (since the larger shard inherits the “vessel” identity). Now: if it’s broken into two seemingly equal halves, both remain tamei because i efshar le-tzamtzem — it’s not actually possible to break it into exact halves; one of them must be the larger, but we can’t tell which, so both retain tumah by safek. The baraita’s payoff: if it were possible to break exactly equal, both would be tahor.
Key Terms:
- כְּלִי חֶרֶס (kli cheres) = Earthenware vessel — purified through being broken.
- לְצַמְצֵם (le-tzamtzem) = “To pinpoint precisely” — to measure or split with exact precision.
Segment 17
TYPE: דיוק וקושיא
The inference: if equal halves could be made, both shards would be tahor. But by Rav (half = majority), each half should be considered a majority — and both should retain tumah! Apparent refutation of Rav.
Hebrew/Aramaic:
הָא אֶפְשָׁר לְצַמְצֵם – טְהוֹרִין, אַמַּאי טְהוֹרִין? זִיל הָכָא אִיכָּא רוּבָּא, זִיל הָכָא אִיכָּא רוּבָּא!
English Translation:
The Gemara infers: But were it possible to measure precisely and divide it into equal halves, both would be pure. If, as Rav states, the halakhic status of half is like that of a majority, why are they pure? Go here, to one half of the vessel, and you will see that there is a majority and it should remain impure, and go there, to the other half, and you will see that there is a majority and it should remain impure.
קלאוד על הדף:
The killer challenge against Rav. The baraita implied that exact equal halves would result in both shards being tahor — but Rav’s principle (mechetza al mechetza ke-rov) yields the opposite: each half would qualify as a “majority” and remain tamei. Zil hakha — ika rubba; zil hakha — ika rubba — go this way, here’s a majority; go that way, here’s a majority. By Rav’s logic, both halves should be considered the dominant majority and stay tamei. This contradicts the baraita’s implied tahor-result and refutes Rav.
Key Terms:
- זִיל הָכָא … זִיל הָכָא (zil hakha … zil hakha) = “Go here … go there” — a Talmudic rhetorical move pointing to two opposing applications of the same principle.
Segment 18
TYPE: תירוץ רב פפא
Rav Pappa rescues Rav: there cannot be two majorities in one vessel — so neither half qualifies. But for shechita-simanim, where there’s no “other majority,” exactly half can equal a majority.
Hebrew/Aramaic:
אָמַר רַב פָּפָּא: תְּרֵי רוּבֵּי בְּחַד מָנָא לֵיכָּא.
English Translation:
Rav Pappa said in rejecting that proof: There are not two majorities in one vessel. Therefore, one cannot consider the halakhic status of half like that of a majority. By contrast, with regard to cutting the windpipe or gullet, the halakhic status of precisely half can be like that of a majority, as there is no other majority contradicting that status.
קלאוד על הדף:
A sharp distinction by Rav Pappa: trei rubei be-chad mana leika — “there are no two majorities in one vessel.” Rav’s rule (half = majority) requires the uniqueness of the half being measured: it can only function as a “majority” if there’s nothing competing. In a kli-cheres broken into equal halves, both halves would compete for the title of “majority” — and since both can’t be the majority simultaneously, neither qualifies. But for shechita, the cut side and the uncut side are not symmetrical competitors — the cut counts as functionally complete (rubo ke-kulo) without facing a counter-majority on the other side. So Rav survives.
Key Terms:
- רַב פָּפָּא (Rav Pappa) = A late Babylonian Amora; a frequent harmonizer of opposing positions.
- תְּרֵי רוּבֵּי בְּחַד מָנָא לֵיכָּא (trei rubei be-chad mana leika) = “There are no two majorities in one entity” — a structural distinction limiting Rav’s principle.
Segment 19
TYPE: תא שמע — תחילת קושיא (גַּרְגֶּרֶת)
The amud cuts off mid-challenge — the gargeret proof has begun: “one who cut half the windpipe and paused…” The continuation and resolution come on 29a.
Hebrew/Aramaic:
תָּא שְׁמַע: שָׁחַט חֲצִי גַרְגֶּרֶת, וְשָׁהָה בָּהּ
English Translation:
The Gemara suggests: Come and hear another proof contrary to Rav’s opinion from a baraita: If one cut half the windpipe and interrupted the slaughter
קלאוד על הדף:
The third item in the mnemonic — gargeret — opens but doesn’t complete on this amud. The baraita’s setup: someone cut half the windpipe and then paused. The implication will be that even after the pause, the slaughter remains discussable — implying that half is not equivalent to a full rov (otherwise the pause-as-sh’hiya question wouldn’t arise). The full force of the challenge unfolds on 29a; the daf ends mid-quotation, leaving the mechetza ke-rov machloket dangling for tomorrow.
Key Terms:
- שָׁהָה בָּהּ (shaha bah) = “Paused [during] it” — the start of a sh’hiya scenario.
