Amud Aleph (52a)
Segment 1
TYPE: המשך הסוגיא — ריסוקי אברים
Continuing the discussion of a bird that fell: which surfaces raise concern for shattered limbs
Hebrew/Aramaic:
חוֹל הַדַּק – לָא חָיְישִׁינַן; חוֹל הַגַּס – חָיְישִׁינַן; אֲבַק דְּרָכִים – חָיְישִׁינַן; תִּיבְנָא וַעֲבִיד בִּזְגָּא – חָיְישִׁינַן; לָא עָבֵיד בִּזְגָּא – לָא חָיְישִׁינַן.
English Translation:
If the bird fell on fine sand, we need not be concerned, because the sand slides on impact, cushioning the fall. If it fell on coarse sand, we must be concerned, because there are large stones mixed into it. If it fell on dust of the road, we must be concerned, because the dust is compact and hard. If the bird fell on bundled straw, we must be concerned, because it is compact and hard. If the straw was not bundled, we need not be concerned.
קלאוד על הדף:
The daf opens by extending the previous discussion of רִיסּוּקֵי אֵבָרִים — shattered limbs from a fall. The governing principle is hardness: a surface that yields and cushions the impact removes the concern, while a hard, compact surface preserves it. Fine sand and unbundled straw are soft enough to absorb the blow; coarse sand (which hides stones), packed road-dust, and bundled straw are hard enough that the internal organs may be ruptured even with no visible wound.
Key Terms:
- רִיסּוּקֵי אֵבָרִים (rissukei eivarim) = shattering/crushing of the internal limbs and organs, rendering the animal a tereifa even without an external wound
- חָיְישִׁינַן (chayshinan) = we are concerned (i.e., we treat it as possibly a tereifa)
- בִּזְגָּא (bizga) = a bundle/sheaf (bundled straw is dense and hard)
Segment 2
TYPE: המשך הסוגיא — כלל המשרקת
Grains and legumes as landing surfaces, and the unifying principle: does it slip?
Hebrew/Aramaic:
חִיטֵּי וְכֹל דְּמִינַיְיהוּ – חָיְישִׁינַן; שְׂעָרֵי וְכֹל דְּמִינַיְיהוּ – חָיְישִׁינַן; כׇּל מִינֵי קִטְנִיּוֹת – אֵין בָּהֶם מִשּׁוּם רִיסּוּקֵי אֵבָרִים, לְבַר מִן רוּבְּיָא. חִימְצֵי – אֵין בּוֹ מִשּׁוּם רִיסּוּק אֵבָרִים, חִפְצֵי – יֵשׁ בּוֹ מִשּׁוּם רִיסּוּק אֵבָרִים. כְּלָלָא דְּמִלְּתָא: כֹּל מִידֵּי דְּמַשְׁרֵיק – אֵין בּוֹ מִשּׁוּם רִיסּוּק אֵבָרִים, לָא מַשְׁרֵיק – יֵשׁ בּוֹ מִשּׁוּם רִיסּוּק אֵבָרִים.
English Translation:
If the bird fell on wheat and all similar types of grain, such as spelt or rye, whose kernels are hard, we must be concerned. If it fell on barley and all similar types of grain, such as oats, we must be concerned. With regard to all types of beans, there is no concern due to possible shattered limbs if a bird fell on them, since their round shape causes the bird to slide when it hits them, except for fenugreek. With regard to peas, there is no concern due to possible shattered limbs, but with regard to chickpeas, there is a concern due to possible shattered limbs. The principle of the matter is: With regard to anything that slips to the sides on impact, there is no concern due to possible shattered limbs. And with regard to anything that does not slip, there is a concern due to possible shattered limbs.
קלאוד על הדף:
The Gemara now generalizes the hardness criterion into a precise mechanical principle. The decisive factor is not hardness alone but whether the surface lets the bird slip on impact (מַשְׁרֵיק): round legumes scatter and dissipate the force, so there is no concern, whereas angular grains and certain seeds hold firm and transmit the blow. The exceptions sharpen the rule — fenugreek and chickpeas are legumes whose shape does not let the bird slide, so they too raise concern.
Key Terms:
- קִטְנִיּוֹת (kitniyot) = legumes — generally round, so a falling bird slides off them
- רוּבְּיָא (rubya) = fenugreek — the one legume that does raise concern
- חִימְצֵי / חִפְצֵי (chimtzei / chiftzei) = peas (no concern) versus chickpeas (concern)
- מַשְׁרֵיק (mashreik) = causes slipping/sliding — the operative test for the whole sugya
Segment 3
TYPE: מחלוקת — הדבוק
Rav Ashi vs. Ameimar on a bird whose wings stuck to a glue-trap board (lishna kama)
Hebrew/Aramaic:
דָּבוֹק – רַב אָשֵׁי שָׁרֵי, אַמֵּימָר אָסַר. בְּחַד גַּפָּא – דְּכוּלֵּי עָלְמָא לָא פְּלִיגִי דִּשְׁרֵי, כִּי פְּלִיגִי בִּתְרֵי גַּפֵּי. מַאן דְּאָסַר אָמַר לָךְ: הֵיכִי נֵיקוּם? וּמַאן דְּשָׁרֵי אָמַר לָךְ: אֶפְשָׁר דְּנֵיקוּם אַעִיקְבֵי דְּגַפֵּי.
English Translation:
If the bird’s wings became stuck to a davuk, a board covered with glue set as a trap, and in trying to escape it fell to the ground while stuck to the board, Rav Ashi deemed the bird permitted, while Ameimar deemed it prohibited. The Gemara explains: In a case where only one wing was stuck to the board, everyone agrees that it is permitted, because the bird flaps with the other wing, lessening the impact of the fall. They disagree when both wings are stuck to the board. The one who deemed it prohibited could have said to you: How will it stand itself up so that it might dampen the impact? And the one who deemed it permitted could have said to you: It is possible for it to stand itself up by using the tips of its wings.
קלאוד על הדף:
The sugya turns to a bird caught on a glue-trap board (davuk). The concern is again rissukei eivarim: if the bird falls while stuck and cannot break its fall, its limbs may shatter. In this first version, the dispute is narrowed to a bird stuck by both wings, where Ameimar says it has no way to right itself and Rav Ashi says it can still steady itself on the tips of its wings; a bird stuck by only one wing is agreed to be permitted, since it flaps with the free wing.
Key Terms:
- דָּבוֹק (davuk) = a board smeared with glue, set as a bird-trap; a bird that gets stuck and falls raises the rissukei eivarim concern
- גַּפָּא (gappa) = a wing
- עִיקְבֵי דְּגַפֵּי (ikvei de-gappei) = the tips/butts of the wings, on which the bird might steady itself to soften the fall
Segment 4
TYPE: לישנא אחרינא — הדבוק
An alternate version of the davuk dispute, plus the final halakha
Hebrew/Aramaic:
וְאִיכָּא דְּאָמְרִי: בִּתְרֵי גַּפֵּי כּוּלֵּי עָלְמָא לָא פְּלִיגִי דַּאֲסִיר, כִּי פְּלִיגִי בְּחַד גַּפָּא. מַאן דְּשָׁרֵי אָמַר לָךְ: אֶפְשָׁר דְּפָרַח בְּחַד גַּפָּא, וּמַאן דְּאָסַר: כֵּיוָן דִּבְהַאי לָא מָצֵי פָּרַח, בְּהַאי נָמֵי לָא מָצֵי פָּרַח. וְהִילְכְתָא: בִּתְרֵי גַּפֵּי אֲסִיר, בְּחַד גַּפָּא שְׁרֵי.
English Translation:
And there are those who say: In a case where two wings were stuck to the board, everyone agrees that it is prohibited, because it cannot dampen the impact. They disagree when only one wing is stuck to the board. The one who deemed it permitted could have said to you: It is possible for it to fly with one wing and dampen the fall. And the one who deemed it prohibited could say: Since it cannot fly with this wing that is stuck to the davuk, it also cannot fly with that untrapped wing. The Gemara concludes: And the halakha is: In a case where two wings were stuck, it is prohibited. In a case where only one wing was stuck, it is permitted.
קלאוד על הדף:
The second version (ve’ika de’amri) inverts the picture: both agree a bird stuck by both wings is prohibited, and the dispute is over a bird stuck by only one wing, where Rav Ashi permits (it flies with the free wing) and Ameimar prohibits (a wing struggling against the glue cannot fly, and the panic disables the other wing too). The two versions disagree about where the line of agreement falls, but the Gemara cuts through with a decisive ruling: two stuck wings are prohibited, one stuck wing is permitted. This pesak effectively splits the difference and becomes the practical halakha.
Key Terms:
- וְאִיכָּא דְּאָמְרִי (ve’ika de’amri) = and there are those who say — a marker introducing an alternate version of the prior exchange
- הִילְכְתָא (hilkheta) = the halakha, the practical legal ruling that resolves the dispute
Segment 5
TYPE: משנה וברייתא — רוב צלעות
Citing the mishna’s “most of its ribs broken” and the baraita defining “most”
Hebrew/Aramaic:
נִשְׁתַּבְּרוּ רוֹב צַלְעוֹתֶיהָ. תָּנוּ רַבָּנַן: אֵלּוּ הֵן רוֹב צְלָעוֹת – שֵׁשׁ מִכָּאן וְשֵׁשׁ מִכָּאן, אוֹ אַחַת עֶשְׂרֵה מִכָּאן וְאַחַת מִכָּאן.
English Translation:
§ The mishna states that if most of an animal’s ribs were fractured, it is a tereifa. The Sages taught: These are most of the ribs: Six from here and six from there, i.e., six on each side, or eleven from here and one from there. Twenty-two ribs are significant for matters of tereifot, eleven on each side. Twelve fractured ribs constitutes a majority.
קלאוד על הדף:
The Gemara now picks up the mishna’s clause that an animal with most of its ribs broken is a tereifa, and a baraita quantifies “most.” Only the 22 large ribs (11 per side) count for tereifot, so a majority means 12 broken — but the count can be distributed as 6+6 or, at the extreme, 11+1. What matters is the total of 12, not how they are split between the two sides.
Key Terms:
- רוֹב צְלָעוֹת (rov tzela’ot) = the majority of the ribs — at least 12 of the 22 significant ribs
- שֵׁשׁ מִכָּאן וְשֵׁשׁ מִכָּאן (shesh mikan ve-shesh mikan) = six from here and six from there, one way of reaching the 12-rib majority
Segment 6
TYPE: מימרא — הגבלות על רוב צלעות
Ze’eiri and R’ Yochanan qualify which fractures count
Hebrew/Aramaic:
אָמַר זְעֵירִי: וּמֵחֶצְיָין כְּלַפֵּי שִׁדְרָה. אָמַר רַבָּה בַּר בַּר חָנָה אָמַר רַבִּי יוֹחָנָן: וּבִצְלָעוֹת גְּדוֹלוֹת שֶׁיֵּשׁ בָּהֶן מוֹחַ.
English Translation:
Ze’eiri says: And this applies only when the ribs were fractured from the half of the rib toward the spine, but not if they were fractured on the other half. Rabba bar bar Ḥana says that Rabbi Yoḥanan says: And this applies only to fractures occurring in large ribs that contain marrow; fractures in small ribs do not render the animal a tereifa.
קלאוד על הדף:
Two Amoraim add qualifications to the rib-fracture rule, each restricting which breaks count toward the majority. Ze’eiri limits it to fractures in the half of the rib nearer the spine, since a break close to the vital spinal connection is what endangers the animal. Rabba bar bar Chana, citing R’ Yochanan, adds that only the large, marrow-bearing ribs count — fractures in the small ribs are not fatal.
Key Terms:
- שִׁדְרָה (shidra) = the spine; the half of the rib nearer the spine is the dangerous zone for fractures
- צְלָעוֹת גְּדוֹלוֹת שֶׁיֵּשׁ בָּהֶן מוֹחַ (tzela’ot gedolot she-yesh bahen mo’ach) = large ribs that contain marrow — the only ribs whose fracture renders the animal a tereifa
Segment 7
TYPE: מחלוקת — נעקרו לעומת נשתברו
Ben Zakkai (via Ulla) vs. R’ Yochanan on dislocated vs. broken ribs
Hebrew/Aramaic:
אָמַר עוּלָּא, בֶּן זַכַּאי אָמַר: נֶעְקְרוּ – בְּרוֹב צַד אֶחָד, נִשְׁתַּבְּרוּ – בְּרוֹב שְׁנֵי צְדָדִין. רַבִּי יוֹחָנָן אָמַר: בֵּין נֶעְקְרוּ בֵּין נִשְׁתַּבְּרוּ – בְּרוֹב שְׁנֵי צְדָדִין.
English Translation:
§ Ulla said that ben Zakkai says: If the ribs were dislocated from the spine, even a majority of one side, i.e., six dislocated ribs, is enough to render the animal a tereifa. Only if the ribs were broken is a majority of both sides necessary. Rabbi Yoḥanan says: Whether they were dislocated or broken, the animal is a tereifa only with a majority of both sides.
קלאוד על הדף:
The Gemara distinguishes two kinds of rib damage: dislocation (ne’ekru — torn out of their socket at the spine) and fracture (nishtabru — broken along the bone). Ben Zakkai, quoted by Ulla, holds that dislocation is the graver injury, so a majority of just one side (six ribs) suffices, while breaking requires a majority of both sides. R’ Yochanan disagrees, treating both forms identically: in either case the animal is a tereifa only with a majority of both sides. This machloket frames the next, lengthy sugya built around Rav’s ruling.
Key Terms:
- נֶעְקְרוּ (ne’ekru) = were dislocated/torn out from the spine — a more severe injury than a clean fracture
- נִשְׁתַּבְּרוּ (nishtabru) = were broken/fractured along the rib bone
- רוֹב צַד אֶחָד / רוֹב שְׁנֵי צְדָדִין (rov tzad echad / rov shnei tzedadin) = a majority of one side versus a majority of both sides
Segment 8
TYPE: מימרא ובעיא — צלע וחוליא
Rav: a rib torn out with its vertebra is a tereifa; Rav Kahana and Rav Asi’s question
Hebrew/Aramaic:
אָמַר רַב: נֶעֶקְרָה צֵלָע וְחוּלְיָא עִמָּהּ – טְרֵפָה. אָמְרִי לֵיהּ רַב כָּהֲנָא וְרַב אַסִּי לְרַב: נֶעֶקְרָה צֵלָע מִכָּאן וְצֵלָע מִכָּאן, וְחוּלְיָא קַיֶּימֶת, מַהוּ? אֲמַר לְהוּ: גִּיסְטְרָא קָאָמְרִיתוּ?!
English Translation:
Rav says: If a rib was dislocated and the attached vertebra was torn out with it, the animal is a tereifa, even if the spinal cord remains intact. Rav Kahana and Rav Asi said to Rav: If a rib was dislocated from here and another rib from there, i.e., both ribs connected to a single vertebra were dislocated, but the vertebra itself remains intact, what is the halakha? Rav said to them: Are you saying that an animal that was sliced in half is a tereifa? This animal is considered to have been sliced and already has the status of a carcass, as it is already considered dead (see 21a).
קלאוד על הדף:
Rav introduces a new tereifa: a single rib torn out together with its vertebra, even though the spinal cord is unharmed. His students Rav Kahana and Rav Asi probe the boundary, asking about two opposing ribs torn out while the shared vertebra stays put. Rav’s sharp reply reframes their case entirely: if a vertebra has lost the ribs on both sides, the carcass is effectively cut through (gistra) and is not merely a tereifa but a neveila — a status worse than what they were asking about. This exchange launches an intricate dialectical sugya reconciling Rav, ben Zakkai/Ulla, and R’ Yochanan.
Key Terms:
- חוּלְיָא (chulya) = a vertebra of the spine
- גִּיסְטְרָא (gistra) = a body sliced/severed through, treated as a carcass (neveila), a status more severe than tereifa
- נֶעֶקְרָה צֵלָע וְחוּלְיָא עִמָּהּ (ne’ekra tzela ve-chulya imah) = a rib dislocated together with its vertebra — Rav’s case of tereifa
Segment 9
TYPE: קושיא ותירוץ — האם רב עצמו אמר גיסטרא
Isn’t Rav’s own case also a gistra? It must be a rib without its vertebra
Hebrew/Aramaic:
וְהָא רַב נָמֵי גִּיסְטְרָא קָאָמַר? כִּי קָאָמַר רַב – צֵלָע בְּלֹא חוּלְיָא.
English Translation:
The Gemara asks: But didn’t Rav also say that a sliced animal is a tereifa, since he said that if a rib was dislocated along with the attached vertebra, the animal is a tereifa? In such a case, the opposite rib is inevitably detached. If so, the animal should be considered a carcass. The Gemara responds: When Rav said that such an animal is a tereifa, he was referring to a case where the rib was dislocated without the vertebra.
קלאוד על הדף:
The Gemara presses Rav’s own ruling: if pulling a rib out with its vertebra inevitably drags the opposite rib loose, then Rav’s tereifa case is itself a gistra (carcass), contradicting his calling it merely a tereifa. The resolution begins to re-read Rav’s words: he must mean a rib torn out without the full vertebra. This sets up successive refinements of exactly what Rav had in mind.
Key Terms:
- צֵלָע בְּלֹא חוּלְיָא (tzela belo chulya) = a rib torn out without its vertebra, so the spine itself stays intact
Segment 10
TYPE: קושיא ותירוץ — צלע וחצי חוליא
But Rav said “rib and vertebra”! Answer: a rib with half its vertebra
Hebrew/Aramaic:
וְהָא צֵלָע וְחוּלְיָא קָאָמַר? צֵלָע וַחֲצִי חוּלְיָא.
English Translation:
The Gemara asks: But didn’t Rav explicitly say his statement with regard to a rib and vertebra that were dislocated? The Gemara responds: Rav meant that if a rib and half its attached vertebra were dislocated, the animal is a tereifa. The opposite rib, however, is intact and connected to the remainder of the vertebra.
קלאוד על הדף:
The previous answer is refined to fit Rav’s actual wording of “rib and vertebra.” The new reading is “a rib and half its vertebra”: only one half of the vertebra is torn away with the rib, so the opposite rib remains anchored to the surviving half. This keeps the case a tereifa rather than a gistra, since the animal is not severed across.
Key Terms:
- צֵלָע וַחֲצִי חוּלְיָא (tzela va-chatzi chulya) = a rib torn out with half of its vertebra, leaving the opposite rib still attached to the other half
Segment 11
TYPE: קושיא — מבן זכאי על דברי רב
By inference the students asked about ribs without vertebrae — yet Rav called it a gistra, contradicting ben Zakkai
Hebrew/Aramaic:
מִכְּלָל דְּרַב כָּהֲנָא וְרַב אַסִּי, צֵלָע בְּלֹא חוּלְיָא אָמְרִי, וַאֲמַר לְהוּ: ״גִּיסְטְרָא קָאָמְרִיתוּ״? וְהָאָמַר עוּלָּא: בֶּן זַכַּאי אָמַר: נֶעְקְרוּ – בְּרוֹב צַד אֶחָד, נִשְׁתַּבְּרוּ – בְּרוֹב שְׁנֵי צְדָדִין.
English Translation:
The Gemara challenges: By inference, one may conclude that Rav Kahana and Rav Asi stated their question with regard to a less serious case, i.e., where a rib from each side was torn out without the vertebra being damaged at all. And yet, Rav said to them: Are you saying that an animal that was sliced in half is a tereifa? Rather, this animal is a carcass and is certainly prohibited. And how could Rav say this? But didn’t Ulla say that ben Zakkai says: If the ribs were dislocated, even a majority of one side is enough to render the animal a tereifa, while if the ribs were broken, a majority of both sides is necessary? If so, any animal with fewer than six dislocated ribs should be kosher, as long as the spine is undamaged.
קלאוד על הדף:
Having established that the students’ case was two ribs dislocated without any vertebral damage, the Gemara now finds Rav’s “gistra” reply shocking: how can a mere two dislocated ribs make a carcass? Ben Zakkai (via Ulla) had ruled that dislocation only renders a tereifa at six ribs (a majority of one side) — so two should not even reach tereifa, let alone carcass status. This sharpens the contradiction that the following lines must resolve.
Key Terms:
- מִכְּלָל (mikelal) = by inference; deducing from the prior answer what the students must have been asking about
- בֶּן זַכַּאי (ben Zakkai) = the Tanna whose ruling (quoted by Ulla) sets the dislocation threshold at six ribs
Segment 12
TYPE: תירוץ — זה כנגד זה
Distinction: ben Zakkai speaks of ribs not opposite each other; Rav of ribs directly opposite
Hebrew/Aramaic:
אָמַר לָךְ: הָתָם זֶה שֶׁלֹּא כְּנֶגֶד זֶה, הָכָא זֶה כְּנֶגֶד זֶה.
English Translation:
The Gemara responds: Rav could have said to you: There, where ben Zakkai says that six dislocated ribs on one side render the animal a tereifa, this is referring only to ribs not dislocated one opposite the other. Here, where Rav says that two dislocated ribs render the animal a carcass, this is referring to ribs dislocated one opposite the other.
קלאוד על הדף:
The contradiction dissolves through a geometric distinction. Ben Zakkai’s six-rib threshold is for ribs scattered along one side, not lined up across from each other; even six such dislocations are only a tereifa. Rav’s two ribs, however, are directly opposite (zeh keneged zeh), so the vertebra between them is stripped on both sides — that is what makes the animal a gistra, regardless of the small number.
Key Terms:
- זֶה כְּנֶגֶד זֶה (zeh keneged zeh) = one directly opposite the other — ribs facing each other across the same vertebra
- זֶה שֶׁלֹּא כְּנֶגֶד זֶה (zeh shelo keneged zeh) = ribs not opposite each other, scattered along the side
Segment 13
TYPE: קושיא — מרבי יוחנן על זה כנגד זה
But R’ Yochanan requires a majority of both sides, which must include opposing ribs — yet he calls it tereifa, not carcass
Hebrew/Aramaic:
וְהָאָמַר רַבִּי יוֹחָנָן: בְּרוֹב שְׁנֵי צְדָדִין, וּבְרוֹב שְׁנֵי צְדָדִין אִי אֶפְשָׁר דְּלָא קָיְימָא (חד) [חֲדָא] מִינַּיְיהוּ זֶה כְּנֶגֶד זֶה!
English Translation:
The Gemara asks: But doesn’t Rabbi Yoḥanan say that the animal is a tereifa only if a majority of both sides was dislocated, and in a majority of both sides, it is impossible that one of them is not situated opposite another? Still, Rabbi Yoḥanan says that the animal is a tereifa and not a carcass.
קלאוד על הדף:
The “opposite each other” distinction now faces a counter-example from R’ Yochanan. He requires a majority of both sides dislocated — and with that many ribs out on both sides, statistically at least one pair must end up directly opposite each other. Yet R’ Yochanan still calls the animal a tereifa, not a gistra. So opposing dislocation by itself cannot be what makes a carcass; another factor must be in play.
Key Terms:
- אִי אֶפְשָׁר דְּלָא קָיְימָא חֲדָא מִינַּיְיהוּ (i efshar de-lo kaima chada minaihu) = it is impossible that not at least one of them ends up opposite another — a statistical inevitability argument
Segment 14
TYPE: תירוץ — בוכנא ואסיתא
Distinction: R’ Yochanan’s case is rib-end without the socket; Rav’s is rib-end with the socket together
Hebrew/Aramaic:
הָתָם – בּוּכְנָא בְּלָא אֲסִיתָא, הָכָא – בּוּכְנָא וַאֲסִיתָא.
English Translation:
The Gemara responds: There, Rabbi Yoḥanan is referring to a case where the pestle, i.e., the end of the rib, was torn out without the mortar, the socket of the vertebra in which it sits, leaving the spine completely intact. In such a case, the animal is a tereifa only if twelve ribs were dislocated, even though this necessarily includes one rib opposite another. Here, where Rav says that two dislocated ribs opposite one another render the animal a carcass, that is referring to a case where the pestle and mortar were torn out together, damaging the spine.
קלאוד על הדף:
The decisive factor is now identified using a vivid pestle-and-mortar image. The rib-end is the pestle (bukhna) and the socket in the vertebra is the mortar (asita). R’ Yochanan’s twelve dislocated ribs come out as bare rib-ends without their sockets, so the spine stays whole and the animal is only a tereifa. Rav’s two opposing ribs, by contrast, are torn out together with their sockets, gouging the vertebra from both sides and severing the spine — hence a gistra.
Key Terms:
- בּוּכְנָא (bukhna) = a pestle; here, the head of the rib that fits into the vertebra
- אֲסִיתָא (asita) = a mortar; here, the socket in the vertebra that holds the rib-head
- בּוּכְנָא בְּלָא אֲסִיתָא / בּוּכְנָא וַאֲסִיתָא (bukhna belo asita / bukhna va-asita) = rib-end without its socket (spine intact) versus rib-end with its socket (spine breached)
Segment 15
TYPE: קושיא ותירוץ — מדוע שאלו בכלל
If so, the students’ case equals Rav’s own ruling — so why ask? Because they had not heard Rav’s statement
Hebrew/Aramaic:
אִי הָכִי, הַיְינוּ דְּרַב? לָא שְׁמִיעַ לְהוּ דְּרַב.
English Translation:
The Gemara asks: If so, why did Rav Kahana and Rav Asi ask anything of Rav? Their case in question is identical to the statement of Rav. If Rav says that the animal is a tereifa if a rib and part of its vertebra were dislocated, that should be the halakha all the more so if ribs opposite one another were dislocated in addition to part of the attached vertebra. The Gemara responds: Rav Kahana and Rav Asi did not hear that statement of Rav.
קלאוד על הדף:
A new difficulty surfaces about the students’ question itself. If their case (opposing ribs torn out with the vertebral sockets) is essentially Rav’s own ruling magnified, then they were asking about something Rav had already taught — so why ask at all? The Gemara answers that Rav Kahana and Rav Asi simply had not yet heard Rav’s statement, so to them the case was genuinely open.
Key Terms:
- הַיְינוּ דְּרַב (haynu de-Rav) = this is the very [ruling] of Rav — the objection that their question merely restates what Rav already held
- לָא שְׁמִיעַ לְהוּ (lo shemi’a lehu) = they had not heard it — the students were unaware of Rav’s prior statement
Segment 16
TYPE: קושיא ותירוץ — מדוע שאלו על שתיים
Why not ask about one rib like Rav’s case? To extract two rulings from a single question
Hebrew/Aramaic:
וְלִיבְעוֹ מִינֵּיהּ כִּדְרַב? סָבְרִי: לִיבְעֵי מִינֵּיהּ חֲדָא דְּפָרֵישׁ לַן תַּרְתֵּי, דְּאִי בָּעֵינַן מִינֵּיהּ חֲדָא, הָנִיחָא אִי אֲמַר לַן ״טְרֵפָה״ – כׇּל שֶׁכֵּן תַּרְתֵּי, אִי אֲמַר לַן ״כְּשֵׁרָה״ – אַכַּתִּי תַּרְתֵּי קָא מִיבַּעְיָא לַן.
English Translation:
The Gemara persists: But if so, let them ask about the simpler case of one dislocated rib, like that which Rav himself discussed. Why ask specifically about two ribs opposite one another? The Gemara responds: They reasoned: Let us ask him one question through which he will explain to us two different cases. As, if we ask him about only one dislocated rib, this works out well if he says to us that the animal is a tereifa, because we can infer that all the more so if two ribs opposite one another are dislocated, the animal is a tereifa. But if he says to us that it is kosher, we must still ask with regard to a case of two dislocated ribs.
קלאוד על הדף:
The Gemara now asks why the students framed their question around two ribs rather than the simpler single rib. The answer reveals a deliberate pedagogical strategy: by choosing the two-rib case, they hoped a single question would settle two halakhot at once. Had they asked about one rib and heard “tereifa,” they would still not know the two-rib case; their chosen framing was designed to be maximally informative.
Key Terms:
- לִיבְעֵי מִינֵּיהּ חֲדָא דְּפָרֵישׁ לַן תַּרְתֵּי (liba’ei minei chada de-fareish lan tartei) = let us ask him one [question] that will clarify two [cases] for us — an economical questioning strategy
Segment 17
TYPE: קושיא — גם שאלת השתיים אינה מכריעה תמיד
But the two-rib question is equally inconclusive: if he says tereifa, the one-rib case is still open
Hebrew/Aramaic:
אִי הָכִי, הַשְׁתָּא נָמֵי דְּקָא בָּעֵי מִינֵּיהּ תַּרְתֵּי, הָנִיחָא אִי אֲמַר לְהוּ ״כְּשֵׁרָה״ – כׇּל שֶׁכֵּן חֲדָא; וְאִי אֲמַר לְהוּ ״טְרֵפָה״, אַכַּתִּי חֲדָא מִיבַּעְיָא לְהוּ.
English Translation:
The Gemara objects: If that is so, then now, too, when they ask him about two ribs, they may not receive an answer with regard to both cases. Granted, this works out well if he says to them that an animal with two dislocated ribs opposite one another is kosher, since they can infer that all the more so it is kosher if only one rib is dislocated. But if he says to them that it is a tereifa, they must still ask with regard to a case of only one dislocated rib.
קלאוד על הדף:
The Gemara turns the symmetry argument against the proposed strategy. The two-rib question is no more guaranteed to settle both cases than the one-rib question: if Rav had answered “kosher,” they could infer the one-rib case (all the more so kosher), but if he answered “tereifa,” the gentler one-rib case would remain unresolved. So the supposed efficiency of asking about two ribs is not airtight.
Key Terms:

Answer: by asking about two, they would provoke Rav’s annoyed answer, revealing the one-rib ruling
Hebrew/Aramaic:
סָבְרִי: אִם כֵּן מִירְתָּח קָא רָתַח. חֲדָא טְרֵפָה, תַּרְתֵּי מִיבַּעְיָא?
English Translation:
The Gemara responds: They reasoned that it is better to ask about a case where two ribs opposite one another were dislocated, because if it is so that Rav holds that the animal is a tereifa if even one rib is dislocated, then he would become angry and respond: If an animal with even one dislocated rib is a tereifa, is it necessary to ask about an animal with two dislocated ribs?
קלאוד על הדף:
The students’ clever reasoning is now exposed: asking about the harder two-rib case was a deliberate lever. If Rav held that even one rib makes a tereifa, the two-rib question would strike him as obviously unnecessary and he would snap back in annoyance — and that very irritation would betray the answer to the one-rib case. The framing was designed to extract both rulings even from a curt or angry reaction.
Key Terms:

But Rav did not appear angry — the answer: “gistra?!” was itself his anger

English Translation:
The Gemara objects: But they did say this question to him and he did not become angry, despite the fact that he holds that even one dislocated rib renders the animal a tereifa. The Gemara responds: When he said to them: Are you saying that an animal that was sliced in half is a tereifa, this is his anger. Rav Kahana and Rav Asi understood from this response that an animal with two dislocated ribs opposite one another is a carcass, but an animal with one dislocated rib is a tereifa.
קלאוד על הדף:
The Gemara resolves the entire reconstruction with a neat reading of Rav’s actual words. The objection notes that Rav did not visibly lose his temper — but the answer is that his retort “Are you asking about a gistra?!” was precisely the irritated response the students anticipated. From it they learned both rulings at once: two opposing ribs make a carcass, while a single dislocated rib (Rav’s own teaching) makes a tereifa. The long dialectic thus closes by validating the students’ strategy.

English Translation:
§ Rabba bar Rav Sheila says that Rav Mattana says that Shmuel says: If a rib was ripped from its root, or if the skull was crushed in its majority, or if the flesh that envelops the majority of the rumen was damaged in its majority, the animal is a tereifa.
קלאוד על הדף:
A new transmission chain delivers three distinct tereifot from Shmuel, each tied to a different organ system. A single rib ripped clean out of its root (me’ikara) renders the animal a tereifa even by itself; so does a skull crushed over most of its area; so does damage to most of the flesh covering most of the rumen. These three rulings, especially the first, become the focus of the rest of the daf, which tests each against parallel mishnayot.
Key Terms:

The Gemara asks: Did Shmuel really say that if a rib was ripped from its root, the animal is a tereifa? But raise a contradiction from a mishna (Oholot 2:3):
קלאוד על הדף:
The Gemara challenges Shmuel’s first ruling — that a rib ripped from its root is a tereifa — by introducing (urminhu) a parallel from a mishna in Oholot dealing with corpse impurity in a tent. That mishna measures spinal deficiency in vertebrae, not ribs, suggesting that mere rib loss may not be decisive. The citation bridges into amud bet, where the full text of the Oholot dispute and its resolution appear.
Key Terms:
- וּרְמִינְהוּ (urminhu) = and raise a contradiction against it — the standard term for confronting a statement with a conflicting source

The Oholot mishna: Beit Shammai vs. Beit Hillel on spinal deficiency, applied to tereifa by Shmuel
Hebrew/Aramaic:
כַּמָּה חִסָּרוֹן בְּשִׁדְרָה? בֵּית שַׁמַּאי אוֹמְרִים: שְׁתֵּי חוּלְיוֹת, וּבֵית הִלֵּל אוֹמְרִים: חוּלְיָא אַחַת, וְאָמַר רַב יְהוּדָה אָמַר שְׁמוּאֵל: וְכֵן לִטְרֵפָה.
English Translation:
How much is considered a deficiency in the spine of a corpse so that it will not be considered a full corpse that would render one impure in a tent? Beit Shammai say: Two missing vertebrae, and Beit Hillel say: One vertebra. And Rav Yehuda says that Shmuel says: And just as Beit Shammai and Beit Hillel disagree with regard to ritual impurity, so too they disagree with regard to a tereifa, i.e., according to Beit Hillel an animal missing only one vertebra is a tereifa. Evidently, Shmuel holds that a missing vertebra renders the animal a tereifa, but a dislocated rib does not.
קלאוד על הדף:
The contradicting Oholot mishna asks how much spinal deficiency disqualifies a corpse from conveying tent-impurity: Beit Shammai say two missing vertebrae, Beit Hillel say one. Rav Yehuda quoting Shmuel transfers this same dispute to tereifot, so according to Beit Hillel one missing vertebra makes the animal a tereifa. The apparent problem is that this measures the spine in vertebrae, implying that a lost rib (without vertebra) does not count — which seems to clash with Shmuel’s earlier ruling that a rib ripped from its root is itself a tereifa.
Key Terms:
- חִסָּרוֹן בְּשִׁדְרָה (chisaron be-shidra) = a deficiency/missing portion in the spine, measured in vertebrae

Resolution: Shmuel’s rib ruling and the vertebra ruling address two different cases
Hebrew/Aramaic:
הָכָא – צֵלָע בְּלֹא חוּלְיָא, הָתָם – חוּלְיָא בְּלֹא צֵלָע.
English Translation:
The Gemara responds: This is not difficult. Here, where Shmuel says that a rib ripped from its root renders the animal a tereifa, he is referring to a case where the rib was torn out without the vertebra. There, where he says that a missing vertebra renders the animal a tereifa according to Beit Hillel, he is referring to a case where the vertebra was missing without the rib being dislocated. But if the rib itself was ripped from its root, the animal is a tereifa.
קלאוד על הדף:
The contradiction is dissolved by recognizing that Shmuel’s two rulings cover different anatomical situations. One ruling concerns a rib torn out while its vertebra stays in place (tzela belo chulya); the other concerns a vertebra missing while its rib remains (chulya belo tzela). Each is independently a tereifa, so there is no conflict — Shmuel never said only vertebrae count.
Key Terms:
- חוּלְיָא בְּלֹא צֵלָע (chulya belo tzela) = a missing vertebra without a corresponding lost rib

English Translation:
The Gemara asks: Granted, with regard to a case where a rib was dislocated without the vertebra, you find this commonly. But how can you find a case of a missing vertebra without a dislocated rib? The Gemara responds: This can occur at the ends of the flanks, where there are vertebrae with no ribs attached to them.
קלאוד על הדף:
The Gemara tests whether the distinction is anatomically realistic. A rib-without-vertebra is easy to picture, but how could a vertebra go missing while its rib stays — every mid-spine vertebra bears ribs? The answer points to the tail-end vertebrae at the ends of the flanks (shilhei kaflei), which carry no ribs, so such a vertebra can be lost on its own.
Key Terms:
- מַשְׁכַּחַתְּ לַהּ (mashkachat lah) = you can find/encounter such a case — testing whether a posited scenario actually exists

English Translation:
Shmuel said that just as Beit Shammai and Beit Hillel disagree with regard to ritual impurity, so too they disagree with regard to a tereifa. Rav Oshaya objects to this statement: But if that is so, then the opinion of Beit Hillel is the more stringent one, as they hold that even one missing vertebra renders the animal a tereifa. Accordingly, let the tanna teach this dispute along with the list of leniencies of Beit Shammai and stringencies of Beit Hillel in tractate Eduyyot. Rav said to him: When the question was asked, it was asked with regard to the ritual impurity of a corpse. That is the source of the dispute between Beit Hillel and Beit Shammai, and on that matter, Beit Shammai constitute the stringent opinion. The parallel disagreement with regard to tereifot is not mentioned explicitly in any mishna or baraita, and it was therefore omitted from the list in tractate Eduyyot.
קלאוד על הדף:
Rav Oshaya raises a meta-objection about the curation of a famous list. Tractate Eduyot collects the rare cases where Beit Shammai are lenient and Beit Hillel stringent; if Shmuel is right that Beit Hillel are stringent on tereifa (one vertebra suffices), this should have made that exclusive list. Rav answers that the underlying dispute was originally posed only about corpse impurity — and there Beit Shammai are the stringent side — so the tereifa application was never an independently recorded ruling and therefore never belonged in Eduyot.
Key Terms:

English Translation:
The Gemara returns to Shmuel’s statement: Or if the skull was crushed in its majority, the animal is a tereifa. Rabbi Yirmeya raises a dilemma: Is this referring to the majority of its height or the majority of its circumference? The Gemara responds: The dilemma shall stand unresolved.
קלאוד על הדף:
Turning to Shmuel’s second tereifa, the crushed skull, R’ Yirmeya asks how “majority” is measured: by the skull’s vertical height or by its horizontal circumference. The two yardsticks could yield different verdicts on the same injury. The Gemara cannot decide and leaves the question teiku — unresolved — so in practice one would rule stringently.
Key Terms:
- רוֹב גּוֹבְהָהּ (rov govhah) = the majority of its height

Rav Ashi’s dilemma on the rumen-covering flesh: torn or removed?

English Translation:
Shmuel also said: Or if the flesh that envelops the majority of the rumen was damaged in its majority, the animal is a tereifa. Rav Ashi raises a dilemma: Is this referring even to a case where the majority of the length of the flesh was torn? Or is it referring only to a case where the majority of the flesh was removed, but if it was torn along the majority of its length the animal remains kosher?
קלאוד על הדף:
Shmuel’s third tereifa, the damaged rumen-covering flesh, prompts Rav Ashi to ask what kind of damage qualifies. Does “damaged in its majority” mean the flesh was merely torn (karua) along most of its length, or specifically removed (natul)? Removal is the more severe injury, so if only that counts, a long tear alone would leave the animal kosher. The Gemara now tries to resolve this from a mishna.
Key Terms:
- קָרוּעַ (karua) = torn — split open along its length but still present
- נָטוּל (natul) = removed/taken away — the flesh is actually gone, a more severe loss

English Translation:
The Gemara responds: Resolve the dilemma from that which we learned in the mishna: If the internal rumen was perforated or most of the external rumen was torn, the animal is a tereifa. And in the West, Eretz Yisrael, they said in the name of Rabbi Yosei, son of Rabbi Ḥanina: The entire rumen is the internal rumen. And if so, which is the external rumen? It is the flesh that envelops the majority of the rumen. Apparently, the animal is a tereifa even if the flesh is torn in its majority.
קלאוד על הדף:
The Gemara proposes to resolve Rav Ashi’s dilemma from a mishna that lists “most of the external rumen torn (nikra)” as a tereifa. According to the Eretz Yisrael (West) tradition reported by R’ Yosei b’R’ Chanina, the whole rumen sac is the “internal rumen,” and the “external rumen” is precisely the enveloping flesh that Shmuel spoke of. Since the mishna uses the verb “torn,” it seems to prove that tearing alone suffices, answering Rav Ashi in favor of karua.
Key Terms:
- כָּרֵס הַפְּנִימִית / הַחִיצוֹנָה (keres ha-penimit / ha-chitzona) = the internal rumen versus the external rumen
- בְּמַעְרְבָא (be-ma’arva) = in the West, i.e., Eretz Yisrael — citing the Land of Israel scholarly tradition

English Translation:
The Gemara rejects the proof: This explanation is meant only to clarify the statement of Shmuel, and Shmuel does not agree with the opinion of Rabbi Yosei, son of Rabbi Ḥanina, as this is what Rabbi Ya’akov bar Naḥmani said that Shmuel said: The case of: Most of the external rumen was torn, mentioned in the mishna, where the animal is a tereifa, is not referring to where the flesh enveloping the majority of the rumen was torn, but rather where the majority of the rumen itself was torn. The internal rumen is the place in the rumen that has no wool, i.e., downy projections on the inside of the rumen. Accordingly, one cannot prove anything about the statement of Shmuel based on an explanation of the mishna offered by Rabbi Yosei, son of Rabbi Ḥanina.
קלאוד על הדף:
The attempted proof collapses because it relied on R’ Yosei b’R’ Chanina’s definition, which Shmuel himself does not share. R’ Yaakov bar Nachmani transmits Shmuel’s own reading: the mishna’s “external rumen” is not the covering flesh but the part of the rumen lacking villi (meilat), and “torn” there refers to the rumen wall itself. Since the mishna, on Shmuel’s terms, is not even talking about the covering flesh, it cannot decide whether tearing or removal of that flesh is the operative standard — so Rav Ashi’s dilemma stands open.
Key Terms:
- מָקוֹם שֶׁאֵין בּוֹ מֵילָת (makom she-ein bo meilat) = a place that has no wool/villi — Shmuel’s identification of the relevant rumen surface
- רַבִּי יַעֲקֹב בַּר נַחְמָנִי (Rabbi Yaakov bar Nachmani) = the tradent who reports Shmuel’s own definition, distinct from the Eretz Yisrael view

English Translation:
§ The mishna states: And an animal that was clawed by a wolf is a tereifa. Rav Yehuda says that Rav says: In the case of an animal, it is a tereifa if it was clawed by any predator from the size of a wolf and upward. And with regard to birds, they are tereifot if they were clawed by any predator from the size of a hawk and upward.
קלאוד על הדף:
The Gemara moves to a new clause of the mishna: derisa, the venomous clawing of a predator, which renders the prey a tereifa. Rav Yehuda quoting Rav generalizes the rule by size: any predator at least as large as a wolf can effectively claw a (small) animal, and any predator at least as large as a hawk (netz) can effectively claw a bird. This opens a long inquiry into exactly which predators qualify and against which prey.
Key Terms:
- דְּרוּסָה (derisa) = clawing by a predator that injects venom (zihara), rendering the prey a tereifa even without a visible perforation

English Translation:
The Gemara asks: What does this statement of Rav, that an animal is a tereifa if it was clawed by a predator at least as large as a wolf, serve to exclude? If we say it serves to exclude a cat that clawed an animal, since it is smaller than a wolf, we already learned in the mishna: And an animal clawed by a wolf is a tereifa. One can infer from this that cats do not render an animal a tereifa. And if you would say: This mishna teaches us that a wolf can also effectively claw a large animal, e.g., cattle, but it may still be that a cat can render a small animal a tereifa, this cannot be; didn’t we learn in the mishna that Rabbi Yehuda says: If it was clawed by a wolf in the case of a small animal, or clawed by a lion in the case of a large animal, the animal is a tereifa?
קלאוד על הדף:
The Gemara probes what new information Rav adds. It cannot simply be excluding a cat, since the mishna’s mention of a wolf already implies smaller animals do not qualify. And if Rav meant to extend a wolf’s reach to large livestock, that conflicts with Rabbi Yehuda’s mishna, which assigns the wolf only to small animals (dakka) and reserves large livestock (gassa) for a lion. The objection sets up a search for Rav’s precise contribution.
Key Terms:
- לְמַעוֹטֵי (lema’utei) = to exclude — asking which case Rav’s wording comes to rule out
- חָתוּל (chatul) = a cat — the candidate for exclusion

English Translation:
And if you would say that Rabbi Yehuda disagrees with the Rabbis, and they hold that a wolf can also render large livestock tereifa by clawing, this too is impossible, as doesn’t Rabbi Binyamin bar Yefet say that Rabbi Ela says: The statement of Rabbi Yehuda in the mishna comes only to explain the statement of the Rabbis?
קלאוד על הדף:
To rescue Rav, one might suggest Rabbi Yehuda actually disagrees with the Rabbis (who might allow a wolf to claw even large livestock), leaving room for Rav to teach something. But this is blocked by Rabbi Binyamin bar Yefet quoting Rabbi Ela: Rabbi Yehuda is not disputing the Rabbis at all, only explaining their intent. If so, the Rabbis too limit the wolf to small animals, and Rav’s statement still seems to add nothing.

The Gemara responds: Are you setting the statement of one man against the statement of another man? Even if Rabbi Ela holds that Rabbi Yehuda comes only to explain the statement of the Rabbis, Rav may still hold that Rabbi Yehuda disagrees with the Rabbis. Or, if you wish, say instead: Actually, everyone agrees that a wolf can render only a small animal a tereifa through clawing. Nevertheless, the statement of Rav serves to exclude a cat from the ability to render even a small animal a tereifa. Lest you say that the mishna taught about a wolf only because this is the manner in which the matter typically occurs, but a cat may in fact render a small animal a tereifa, Rav teaches us that it is referring specifically to a wolf.
קלאוד על הדף:
The Gemara offers two ways out. First (gavra a’gavra ka ramit): one may not pit Rav against R’ Ela, since Rav is free to read R’ Yehuda as disputing the Rabbis even if R’ Ela does not. Alternatively, even granting that a wolf only claws small animals, Rav’s statement still has work to do: it teaches that a cat cannot claw even a small animal — pre-empting the assumption that the mishna named a wolf merely as the typical case while a cat might also qualify.
Key Terms:

אָמַר רַב עַמְרָם אָמַר רַב חִסְדָּא: דְּרוּסַת חָתוּל וּנְמִיָּיה בִּגְדָיִים וּטְלָאִים, דְּרוּסַת חוּלְדָּה בְּעוֹפוֹת. מֵיתִיבִי: דְּרוּסַת חָתוּל, נֵץ וּנְמִיָּיה עַד שֶׁתִּינָּקֵב לֶחָלָל, אֲבָל דְּרוּסָה לֵית לְהוּ!
English Translation:
§ Rav Amram says that Rav Ḥisda says: If an animal was clawed by a cat or a mongoose, in the case of kids or lambs, which are very small, it is a tereifa. If it was clawed by a weasel in the case of birds, it is a tereifa. The Gemara raises an objection from a baraita: An animal clawed by a cat, hawk, or mongoose is not rendered a tereifa until one of its internal organs is perforated to its recesses. One may infer: But they, i.e., a cat, hawk, and mongoose, do not have the ability to render an animal a tereifa through the clawing itself.
קלאוד על הדף:
Rav Chisda refines the size principle downward for the smallest prey: a cat or mongoose (nemiya) can claw kids and lambs, and a weasel (chulda) can claw birds. A baraita immediately challenges this, ruling that a cat, hawk, or mongoose makes the prey a tereifa only if it actually perforates an internal organ — implying their clawing alone (without perforation) is ineffective. This contradiction drives the rest of the sugya.
Key Terms:
- נְמִיָּיה (nemiya) = a mongoose
- חוּלְדָּה (chulda) = a weasel
- עַד שֶׁתִּינָּקֵב לֶחָלָל (ad she-tinakev le-chalal) = until [an organ] is perforated through to the body cavity — the baraita’s stricter requirement

Can a hawk really not claw? The baraita and mishna are reconciled: birds vs. kids/lambs
Hebrew/Aramaic:
וְתִסְבְּרָא נֵץ לָא דָּרֵיס? וְהָתְנַן: וּדְרוּסַת הַנֵּץ! הָא לָא קַשְׁיָא: כָּאן בְּעוֹפוֹת, כָּאן בִּגְדָיִים וּטְלָאִים.
English Translation:
The Gemara questions the inference: And can you understand that a hawk does not effectively claw an animal? But didn’t we learn in the mishna: And a small bird clawed by a hawk is rendered a tereifa? The Gemara responds: That is not difficult. Here, where the mishna states that a hawk can effectively claw, it is with regard to birds, while there, where the baraita states that a hawk does not effectively claw, it is with regard to kids and lambs.
קלאוד על הדף:
Before accepting the baraita’s full implication, the Gemara catches an internal tension: the mishna explicitly lists clawing by a hawk as effective, contradicting the inference that a hawk cannot claw. The resolution is by prey-type — a hawk can claw birds (the mishna) but not kids and lambs (the baraita). This narrows the dispute but leaves Rav Chisda’s claim about the cat still exposed.
Key Terms:
- כָּאן בְּעוֹפוֹת, כָּאן בִּגְדָיִים וּטְלָאִים (kan be-ofot, kan bi-gedayim u-telaim) = here with birds, there with kids and lambs — resolving the apparent contradiction by distinguishing the prey

Rav Chisda follows the Beribi, who holds a cat does claw where there are rescuers
Hebrew/Aramaic:
מִכׇּל מָקוֹם, לְרַב חִסְדָּא קַשְׁיָא, הוּא דְּאָמַר כִּי הַאי תַּנָּא, דְּתַנְיָא: בְּרִיבִּי אוֹמֵר: לֹא אָמְרוּ אֵין דְּרוּסָה אֶלָּא בְּמָקוֹם שֶׁאֵין מַצִּילִין, אֲבָל בִּמְקוֹם שֶׁיֵּשׁ מַצִּילִין – יֵשׁ דְּרוּסָה.
English Translation:
The Gemara returns to its initial objection: In any case, the baraita poses a difficulty for Rav Ḥisda, who says that a cat may render kids and lambs tereifot through clawing. The Gemara responds: Rav Ḥisda states his opinion in accordance with the opinion of that tanna, as it is taught in a baraita: The Distinguished One says: They said that a kid is not effectively clawed by a cat only in a place where there are none present to save it. But in a place where there are bystanders trying to save the kid, it is effectively clawed, since the cat is angered and injects venom into the wound. Rav Ḥisda is referring specifically to the latter case.
קלאוד על הדף:
The Gemara defends Rav Chisda by aligning him with a specific Tanna, the Beribi (the Distinguished One). The Beribi distinguishes by circumstance, not size: a cat fails to claw effectively only where there are none to rescue the prey, but where rescuers are present, the cat is provoked, becomes enraged, and injects venom — so its clawing does render the prey a tereifa. Rav Chisda thus speaks of the rescuer-present scenario, dissolving the baraita’s objection.
Key Terms:
- בְּרִיבִּי (Beribi) = the Distinguished One — an honorific title for a great sage whose baraita is cited here
- מַצִּילִין (matzilin) = those who rescue/save the prey; their presence enrages the cat and activates its venom
- אֵין דְּרוּסָה אֶלָּא… (ein derisa ela…) = there is no [effective] clawing except [under specified conditions] — the Beribi’s qualification

Objection from the hen incident: a cat clawed even with no rescuers present
Hebrew/Aramaic:
וּבִמְקוֹם שֶׁאֵין מַצִּילִין אֵין דְּרוּסָה? וְהָא הָהִיא תַּרְנְגוֹלְתָּא דַּהֲוַאי בֵּי רַב כָּהֲנָא, דִּרְהַט חָתוּל בָּתְרַהּ, וְעָל לְאִידְּרוֹנָא, וְאִיתְּחִיד דַּשָּׁא בְּאַפֵּיהּ, וּמַחְיֵיהּ לְדַשָּׁא בְּסִיחוּפֵיהּ, וְאִשְׁתְּכַח עֲלַהּ חַמְשָׁה קוּרְטֵי דְּמָא!
English Translation:
The Gemara asks: And in a place where there are none to save the kid, is it not effectively clawed? But there was a certain hen that was in the house of Rav Kahana, which a cat pursued, and the cat entered after it into a small room, and the door shut in the cat’s face, and it struck the door with its paws in anger. And afterward, five drops of blood, i.e., venom, were found on the door. Apparently a cat is venomous even if no one is present to save its prey.
קלאוד על הדף:
The Beribi’s view (that a cat only claws effectively where rescuers are present) is challenged by a striking incident from Rav Kahana’s house. A cat chasing a hen got shut in a room with no one to interfere, yet in its frustration it struck the door and left five drops of venom-blood — proof that a cat can become enraged and venomous even with no rescuers around. This empirical anomaly forces the next clarification.
Key Terms:
- תַּרְנְגוֹלְתָּא (tarnegolta) = a hen
- חַמְשָׁה קוּרְטֵי דְּמָא (chamisha kurtei dema) = five drops of blood — taken to be the cat’s venom (zihara) discharged in anger
- סִיחוּפֵיהּ (sichufeih) = with its overturning/striking force — the cat slamming the door

Self-rescue counts like rescue by others; the Rabbis hold the cat’s venom does not burn enough
Hebrew/Aramaic:
הַצָּלַת עַצְמָהּ נָמֵי כְּהַצָּלַת אֲחֵרִים דָּמֵי, וְרַבָּנַן – זִיהֲרָא אִית לֵיהּ, וְלָא קָלֵי זִיהֲרֵיהּ.
English Translation:
The Gemara responds: For a cat, saving itself is also considered like saving others. Since the cat felt threatened, it acted as it would if there had been someone present to defend the hen. The Gemara asks: And the Rabbis, who state in the baraita that a cat can never effectively claw a small animal, even when there are bystanders attempting to save its prey, how do they explain this incident? The Gemara responds: According to the Rabbis, a cat does have venom, but its venom does not burn enough to render the animal a tereifa.
קלאוד על הדף:
The hen incident is reconciled with the Beribi by a key principle: a cat saving itself is treated like the case of others saving the prey (hatzalat atzmah ke-hatzalat acheirim) — the cat’s own sense of being trapped enrages it just as a rescuer would. The Gemara then asks how the Rabbis (who deny any effective cat-clawing) handle the venom on the door, and answers that the Rabbis concede the cat has venom (zihara) but hold it is not potent enough (does not burn, lo kalei) to make the prey a tereifa.
Key Terms:
- הַצָּלַת עַצְמָהּ כְּהַצָּלַת אֲחֵרִים (hatzalat atzmah ke-hatzalat acheirim) = saving oneself is like being saved by others — both equally enrage the cat
- זִיהֲרָא (zihara) = venom — the toxin a predator injects when clawing
- לָא קָלֵי זִיהֲרֵיהּ (lo kalei zihareih) = its venom does not burn/scorch [enough] to render the prey a tereifa

Alternate version: the baraita follows the Beribi, who limits clawing to where there ARE rescuers
Hebrew/Aramaic:
אִיכָּא דְאָמְרִי: הָא מַנִּי? בְּרִיבִּי הִיא, דְּתַנְיָא: בְּרִיבִּי אוֹמֵר: לֹא אָמְרוּ יֵשׁ דְּרוּסָה אֶלָּא בִּמְקוֹם שֶׁיֵּשׁ מַצִּילִין, אֲבָל בִּמְקוֹם שֶׁאֵין מַצִּילִין – אִין דְּרוּסָה.
English Translation:
There are those who state the details of this exchange differently: After raising an objection to the statement of Rav Ḥisda from the baraita that states that a cat cannot effectively claw kids and lambs, the Gemara responds: In accordance with whose opinion is this baraita? It is in accordance with the opinion of the Distinguished One, as it is taught in a baraita: The Distinguished One says: They said that a kid is effectively clawed by a cat only in a place where there are bystanders present to save it. But in a place where there are none present to save the kid, it is not effectively clawed. The baraita, then, discusses a case where there are none present to save it. Rav Ḥisda agrees with the Rabbis that a cat can effectively claw an animal even when there are none present to save it.
קלאוד על הדף:
The second formulation (ika de’amri) inverts the roles. Here it is Rav Chisda who sides with the Rabbis, holding that a cat claws effectively even without rescuers, while the objecting baraita reflects the Beribi — who, in this version, says a cat claws only where there ARE rescuers and not where there are none. The exchange thus assigns the lenient-on-clawing position to the Beribi and the stricter (always-effective) position to Rav Chisda and the Rabbis, the reverse of the first version.
Key Terms:
- הָא מַנִּי? (ha mani?) = whose opinion is this [baraita]? — locating an anonymous source within a known dispute
- לֹא אָמְרוּ יֵשׁ דְּרוּסָה אֶלָּא בִּמְקוֹם שֶׁיֵּשׁ מַצִּילִין (lo amru yesh derisa ela bi-mkom she-yesh matzilin) = effective clawing was stated only where there are rescuers — the Beribi’s position in this version

The hen incident is raised again, and resolved again by self-rescue counting as rescue by others

English Translation:
The Gemara asks: But in a place where there are none present to save the kid, is it not effectively clawed? But there was a certain hen that was in the house of Rav Kahana, which a cat pursued, and the cat entered after it into a small room, and the door shut in the cat’s face, and it struck the door with its paws in anger. And afterward, five drops of blood, i.e., venom, were found on the door. The Gemara responds: For a cat, saving itself is also considered like saving others.
קלאוד על הדף:
Within the second version, the same hen incident is brought to challenge the Beribi’s claim that a cat does not claw effectively where no rescuers are present. The resolution is identical to the first version: the cat’s self-rescue (its panic at being trapped) is treated like rescue by others, so its venom is activated even with no human present. The story thus serves both versions, establishing the principle that a cornered predator’s self-defense triggers the same venom-laden derisa as external interference.
Key Terms:
- אִידְּרוֹנָא (idrona) = a small inner room/chamber — where the cat became trapped
- הַצָּלַת עַצְמָהּ כְּהַצָּלַת אֲחֵרִים (hatzalat atzmah ke-hatzalat acheirim) = saving oneself is like being saved by others — the resolving principle reused here
