Rosh Kollel: Rabbi Mordecai Kornfeld
(a) On what grounds did Rav Ivya the elder query Rav Huna, when he ruled that one may Shecht on Yom-Tov, an animal that is owned jointly by a Jew and a Nochri?
(b) What strange answer did Rav Huna give him?
(c) Why did he do that? Why did he not answer Rav Ivya properly?
(d) What is the correct answer?
(a) Seeing as Rav Chisda agrees with Rav Huna in the previous case, why does he then go on to forbid baking a dough that is jointly owned by a Jew and a Nochri?
(a) What is 'Iysas Kelavim'?
(b) Under what condition is Iysas Kelavim considered bread with regard to Chalah, an Eruv etc. and fulfilling one's obligation on Pesach?
(c) In which other three regards is it considered bread?
(d) According to what we learned earlier ("Lachem" - v'Lo ... li'Kelavim') what reason do we initially give for this dough being permitted (to bake on Yom-Tov), in spite of the fact that a dough that is jointly owned by a Jew and a Nochri, is forbidden?
(a) According to Rabah, someone who bakes on Yom-Tov after he has already eaten, does not receive Malkus. Why not?
(b) What does Rav Chisda say?
(c) But we just established that Rav Chisda too, holds of 'Ho'il'? So how will we now explain the Beraisa, which permits baking Iysas Kelavim on Yom-Tov, according to him?
(a) We learned earlier that Rav Chisda forbids baking a dough that is jointly owned by a Jew and a Nochri on Yom-Tov. What does Rav Huna say about Jewish villagers (who were obligated to supply the local soldiers with food) baking bread (for them) on Yom-Tov?
(b) What did Shimon ha'Teimani and the Jews of the town do when a band of robbers was ransacking their town? What does 'ha'Teimani' mean?
(c) What did Rebbi Yehudah ben Bava say to him?
(d) How do we reconcile this with Rav Huna, who just ruled that, under similar circumstances, one may bake a dough on behalf of Nochrim?
(a) Does the fact that a Tereifah animal is anyway fit for dogs make any difference to the above Halachah?
(b) On what grounds does Rebbi Akiva preclude cooking for Nochrim (from "Lachem"), but not dogs?
(a) According to Rebbi Yosi Hagelili, who forbids performing a Melachah for animals, what is the problem with date-stones?
(b) We answer that the stones are fit to be used as fuel for a fire. Will they still be permitted even if they are very wet?
(c) How about feeding them to one's animals on Shabbos?
(d) Since when is one permitted to use bread in this way?
(a) Rav Huna, who previously permitted baking for a Nochri on Yom-Tov, a loaf that one could eat oneself, disagrees with Rebbi Yehoshua ben Levi. What does Rebbi Yehoshua ben Levi say with regard to inviting a Nochri on Shabbos and Yom-Tov?
(b) Why is Rav Acha bar Yakov strict even with regard to inviting a Nochri on Shabbos?
(c) What is the difference between the leftovers of the cup of a Jew and that of a Nochri?
(d) Seeing as one is permitted to move a coal-shovel with ashes on it on Shabbos (even if there are pieces of wood on it, too), why may one not move the cup which contains the remains of wine and bread? Why should they not be Batel to the cup, in the same way as the shovel is Batel to the ashes?
(a) What is a 'Graf shel Re'i'?
(b) Why may one not then invite the Nochri, and, when the time comes, throw away the remnants in the cup, because they constitute a 'Graf shel Re'i'?
(c) Rava permits inviting a Nochri on Shabbos, like Rebbi Yehoshua ben Levi. What did Mereimar and Mar Zutra tend to tell uninvited Nochrim who arrived on Yom-Tov?
(a) Under what condition do Beis Shamai permit heating water to wash one's feet on Yom-Tov?
(b) What do Beis Hillel say?
(c) The Tana of our Mishnah permits making a fire by which to warm oneself. Why might even Beis Shamai (who do not hold of 'Mitoch') agree with this?
(d) Who in fact, is the author of our Mishnah, Beis Shamai or Beis Hillel?
(a) Raban Gamliel in our Mishnah permits neither Hatmanah (wrapping hot food on Yom-Tov that falls on Friday) nor picking up a metal Menorah that fell down on Yom-Tov (which will be explained in the course of the Sugya). Which is the third ruling that he makes like Beis Shamai?
(b) What did the Chachamim say to him when he cited his father's household as his source for this third ruling?
(a) Beis Shamai and Beis Hillel dispute whether or not, one may wrap on Yom-Tov for Shabbos. What problem do we have with this?
(b) Rav Huna establishes our Mishnah when the owner did not prepare an Eruv Tavshilin. Then what is Beis Hillel's reason for permitting Hatmanah?
(c) What do some opinions permit in this case, besides cooking, baking wrapping and kindling a light on Yom-Tov for Shabbos?
