in memory of Reb David ben Aharon Ha'Levi Rosenwald z"l

Rosh Kollel: Rabbi Mordecai Kornfeld
(a) Rav Huna bar K'tina quoting Resh Lakish, lists three defects. What does he mean when he refers to ...
1. ... 'P'gimas Etzem ba'Pesach'?
2. ... 'P'gimas Ozen bi'Bechor'? Why does Resh Lakish mention specifically the ear? Is it to preclude other Mumin?
3. ... 'P'gimas Mum be'Kodshim'?
(b) Why does the Tana list both 'P'gimas Ozen bi'Bechor' and 'P'gimas Mum be'Kodshim'. Why does he not include ...
1. ... the latter in the former?
2. ... the former in the latter?
(c) Rav Chisda includes P'gimas Sakin in the list of defects. Why does Resh Lakish omit it?
(d) Resh Lakish gives the Shi'ur of all these as 'K'dei P'gimas Mizbe'ach'. What is that equivalent to in practical terms?
(a) Rebbi Shimon in a Beraisa gives the Shi'ur of P'gam on the Mizbe'ach as a Tefach. What does Rebbi Eliezer ben Ya'akov say?
(b) How do we reconcile Resh Lakish's Shi'ur of 'K'dei she'Tachgor bah Tziporen' with those mentioned in the Beraisa?
(a) According to Rav Huna, a Shochet who declines to show his knife to the Rav, is placed in Cherem. What does Rava add to that?
(b) What do we mean when we say that the two opinions do not argue?
(c) Ravina is more stringent than Rava. According to him, what does one add to Rava's ruling in a case where the Shochets knife is found to be Pasul?
(a) Why did Rava bar Chin'na ask Mar Zutra and Rav Ashi to check out his ruling, after he had revoked the Hechsher of a certain butcher who had failed to show him his knife, and declared the animal T'reifah?
(b) What merit did Rav Ashi discover on the butcher's behalf?
(c) What was Rava bar Chin'na's error?
(d) How did Rav Ashi justify revoking the ruling of Rava bar Chin'na (who was a highly respected Zakein) and putting him to shame?
(a) What does Rabah bar Rav Huna rule with regard to Shechting with a detached tooth or finger-nail?
(b) What does he mean by a 'detached' tooth?
(c) We query Rabah bar Rav Huna however, from our Mishnah, which invalidates both of these, as well as a sickle and a saw, because they strangle (i.e. tear out) the Si'manim, instead of cutting them. How do we reconcile with our Mishnah, Rabah bar Rav Huna's ruling concerning ...
1. ... a tooth?
2. ... a finger-nail?
(d) How can Shechitah performed with a tooth or a nail be Kasher, seeing as it is less wide than the neck?
(a) Beis-Shamai in our Mishnah, invalidates Shechitah with a sickle that was performed by Holachah only. What do Beis-Hillel say?
(b) In which case will even Beis Shamai concede that one may Shecht with a sickle, even Lechatchilah?
(c) How does Rebbi Chiya bar Aba Amar Rebbi Yochanan qualify Beis-Hillel's ruling? What do the Mishnah mean when it says 'Beis-Hillel Machshirin'?
(d) What is the reason for this Chumra?
(a) How does Rav Ashi try to prove Rebbi Yochanan's statement from the Lashon of the Mishnah 'Beis Shamai Osrin, Beis-Hillel Machshirin'? What should the Mishnah otherwise have said?
(b) How do we counter Rav Ashi's proof? What ought the Mishnah to have said, according to his contention?
(c) So what do we conclude? What does 'Poslin' and 'Machshirin' mean?
(d) Why is the Halachah nevertheless like Rebbi Yochanan?
(a) Our Mishnah now discusses Hagramah. What does the Tana say about someone who Shechts within the Taba'as ha'Gedolah (the large laryngeal cartilege)?
(b) Rebbi Yossi b'Rebbi Yehudah is more lenient than the Tana Kama. What does he say?
(c) What is the basis of their Machlokes?
(d) What will be the Din if the Shochet Shechts between two Taba'os?
(e) According to some commentaries, Rebbi Yossi bar Yehudah and the Rabbanan argue over completing the Shechitah outside any of the Taba'os. On what grounds do we refute that explanation?
(a) Like whom do Rav and Shmuel both rule?
(b) What do Rav and Shmuel initially say with regard to Shechting the other Taba'os?
(c) Why is that?
(d) We query Rav and Shmuel (in this last point), from a Beraisa. What does the Beraisa say?
(e) The Beraisa continues 'u'Mugremes Pesulah'. What is it referring to? Who is the author?
(a) The Beraisa concludes 'He'id Rebbi Chanina ben Antignos al Mugremes she'Hi Kesheirah'. What does he mean by that?
(b) To answer the Kashya on Rav and Shmuel, Rav Yosef explains 'Rebbi Yossi bar Yehudah Tarti Ka'amar ... '. What does he mean?
(c) What problem do we have with this from the actual words of Rav and Shmuel?
(d) How do we resolve it?
(a) According to others, even Rav and Shmuel agree that Rebbi Yehudah b'Rebbi Yossi is Machshir the other Taba'os no less than the Taba'as ha'Gadol. Then what do they mean when they confine his statement to the Taba'as ha'Gadol? What does he then consider Pasul, according to them?
(b) What is then his reason?
(c) On what grounds do we refute this explanation ...
1. ... per se?
2. ... from the Kashya that we asked on Rav and Shmuel from the Reisha of the Beraisa?
(a) Rebbi Zeira ate from a Mugremes of Rav and Shmuel. What does this mean?
(b) On what grounds did they query Rebbi Zeira?
(c) He replied that the quote in the name of Rav and Shmuel was said by Rav Yosef bar Chiya. So what if it was? Who was Rav Yosef bar Chiya?
(d) In reply, Rav Yosef, who was not too pleased when he heard what Rebbi Zeira had said about him, countered that he had heard it from none other than Rav Yehudah. So what if he had? What was special about Rav Yehudah?
(a) To illustrate this, how did Rav Yehudah quote Rebbi Yirmiyah bar Aba regarding the Halachah of three that are required to permit a B'chor, when he forgot whom Rebbi Yirmiyah bar Aba had quoted?
(b) Which Halachah was Rav Yehudah quoting?
(c) We nevertheless query what Rebbi Zeira did, from a Mishnah in Pesachim. What does the Mishnah say about changing a Minhag?
(a) Abaye answers that the Mishnah in Pesachim refers to someone who traveled from Bavel to Bavel, from Eretz Yisrael to Eretz Yisrael or from Eretz Yisrael to Bavel, but not to someone who traveled from Bavel to Eretz Yisrael. Why is that?
(b) In which area were the B'nei Bavel subservient to the B'nei Eretz Yisrael, besides Kidush ha'Chodesh and Ibur Shanah (which could only be fixed in Eretz Yisrael)?
(c) Rav Ashi justified what Rebbi Zeira did, even if he had traveled from Eretz Yisrael to Bavel. Why is that?
(d) How do we reconcile the Rabbanan from Mechuza (in Bavel), who quoted Rav Nachman, who in turn, declared the Mugremes of Rav and Shmuel, Kasher, with Rav and Shmuel?
(a) What objection did Rebbi Yochanan raise, when Resh Lakish declared Kasher an animal whose Kova (thyroid cartilage, which is beyond the Taba'as ha'Gadol) had been cut in the course of the Shechitah?
(b) Rav Papi in the name of Rava rules that if one Shechted as far as the Chiti ('Paga be'Chiti'), the animal is T'reifah. What are the 'Chiti'?
(c) What do we try to prove from the Pasuk ...
1. ... in Melachim (in connection with Benayahu killing Yo'av) "Vayifga bo Vayamos"?
2. ... in Vayeitzei (in connection with Ya'akov) "Vayifge'u bo Mal'achei Elokim''?
(d) Rav Papa in the name of Rava declared 'Shiyer be'Chiti', Kasher, and that is also the opinion of Rav Chiya b'rei de'Rav Ivya and Mar Zutra. What does 'Shiyer be'Chiti' mean?
(a) Mar bar Rav Ashi disagrees. What does he say?
(b) What is the final ruling in the matter? What is the 'Shipuy Kova'?
(c) Whereabouts is the Shipuy Kova situated?
