Chulin 51

CHULIN 51-54 - sponsored by Dr. Lindsay A. Rosenwald of Lawrence NY, in honor of his father, David ben Aharon ha'Levy Rosenwald of blessed memory.


(a) What does the Beraisa say about a needle in the Beis ha'Kosos (see Tosfos DH 'Machat') that has pierced ...
  1. ... only the inner skin?
  2. ... the outer skin as well?
(b) In which case will the animal remain Kasher even if the needle pierced both skins?

(c) In the case where the needle pierced both skins and there was a drop of blood, what does the Tana say with regard to where a crust ...

  1. ... formed over the wound?
  2. ... did not form over the wound?
(d) On what grounds does the Tana require a drop of blood on the wound particularly in this case, and not in any other?
(a) What did Rav Safra tell Abaye about a certain Rav Avira who had arrived from Eretz Yisrael, that aroused Abaye's curiosity? What strange ruling did he cite in the name of Rebbi?

(b) What did Abaye do when Rav Avira refused ...

  1. ... to come to him?
  2. ... to come down from the roof?
(c) What did he say to Rav Avira when he finally met him face to face?

(d) What was Rav Avira's connection with Rebbi?

(a) What were Rav Nachman from Tzipori and Rebbi Yossi from Madai doing when the She'eilah with the needle in the Beis ha'Kosos was brought to Rebbi?

(b) Where did Rebbi find the drop of blood?

(c) Why did he then declare the animal Tereifah?

(d) What was Abaye's reaction when he heard that?

(a) What does Rav Huna say about an animal that one left standing on the roof, and that one subsequently finds on the ground?

(b) Why is that?

(c) What did Ravina's goat do when, standing at the edge of a skylight, it took a fancy to some peeled barley that it saw directly below the skylight?

(d) Why did Rav Ashi think that this case might be ...

  1. ... worse than the case of Rav Huna, in which case the animal would have been Tereifah?
  2. ... comparable to that of Rav Huna, in which it would have been Kasher?
(a) When a sheep from the flock belonging to Rav Chaviva was seen dragging its hind legs behind it, Rav Yeimar thought that it merely had cramp, and was Kasher.
What did Ravina suggest?

(b) When they examined the animal, what did they find wrong with it?

(c) Why is the Halachah nevertheless like Rav Yeimar?

(a) What does Rav Huna say about rams that indulge in a goring match, in which the animals actually hurt each other?

(b) Under which circumstances does he concede that we do suspect Risuk Eivarim?

(a) What did the ram thieves used to do that gave rise to the fear that the rams' limbs were crushed?

(b) Then why were the Chachamim not afraid of that?

(c) In that case, why were they afraid of crushed limbs when they threw them back?

(d) Under which circumstances are we not afraid even then?

(a) What does Rav Yehudah Amar Rav say about someone who strikes an animal with a stick that reaches all the way down its back ...
  1. ... from its head to its tail?
  2. ... from its tail to its head?
(b) We do however suspect that its back might indeed be broken, if the stick does not reach to the end of its back.
What sort of stick would one have to use, to render the animal Tereifah, even if it did?

(c) Under which circumstances would the animal be Tereifah, even if one were to use a long, straight stick containing no twigs?

Answers to questions



(a) What does Rav Nachman mean when he says that the womb is not subject to Risuk Eivarim?

(b) What would we have to do if it was?

(c) How does Rava try to support Rav Nachman's statement from the Beraisa which states that a one-day old baby is subject to Tum'as Zav?

(d) How do we establish the Beraisa to refute Rava's proof?

(a) We try to bring the same proof for Rav Nachman from the Beraisa which permits Shechting a calf on Yom-Tov, and give the same refutation. What does another Beraisa say about a Bechor that is born on Yom-Tov with a blemish (regarding the Din of Muktzah)?

(b) This too, appears to support Rav Nachman.
Why can we not refute that proof in the same way as we refuted the proofs from the previous Beraisos?

(c) So how do we establish the Beraisa, in order to refute it?

(a) And what does Rav Nachman say about an animal that is thrown down in the slaughterhouse?

(c) What does Rav Yirmiyah bar Acha Amar Rav say about an animal that, after falling from the roof ...

  1. ... stretches out its foreleg in order to stand up?
  2. ... moves its hind leg with the intention of starting to walk?
(d) What does Rav Chisda add to this?
(a) According to Ameimar in the name of Rav Dimi from Neherda'a, an animal that fell from the roof requires examination of its intestines.
Why is that? What are we afraid may have happened?

(b) Mar Zutra citing Rav Papa, is even more strict.
What does he say?

(c) On what grounds did Rav Ashi exempt the Shochet from examining the Simanim?

(a) What does Rav Yehudah Amar Shmuel say about a bird that is thrown into the water by force? How will one know without examining it that it is Kasher?

(b) How does he qualify this ruling? When will swimming not eliminate the need to examine the bird?

(c) How about a case where the bird swims on a straight, where the water is still?

(d) Under which circumstances will we declare the bird Kasher, even if it swam down stream?

(a) What does Rav Yehudah Amar Rav say about a bird that falls into a cloth that is tied to four posts if it (the cloth) is ...
  1. ... loose?
  2. ... tight?
(b) Under which circumstances will the bird be Kasher even though the cloth is tight?

(c) If a bird falls in to ...

  3. ... ashes that have been sifted and ashes that haven't?
  4. ... soft sand and hard sand (i.e. pebbles)?
(b) And what does he say about a bird falling into the earth in the street?

(c) And what distinction does he draw between ...

  1. ... straw of wheat or barley that has been made into a bundle, and straw that has not?
  2. ... wheat and species of wheat (i.e. rye) and barley and species of barley (i.e. oats and spelt)?
  3. ... legumes and fenugreek?
