prepared by Rabbi Eliezer Chrysler of Kollel Iyun Hadaf, Yerushalayim
Rosh Kollel: Rabbi Mordecai Kornfeld
(a) Why is one permitted to make an Eruv on foot on the second day (i.e. on Shabbos), after having made one with food on the first (i.e. on Yom-Tov), but not vice-versa?
(b) Under which condition is one permitted to make an Eruv with bread on the second day, after having made it with bread on the first?
(c) Rav Ashi proves this from our Mishnah, which specifically mentions using the same loaf on the second day. Why do not Amora'im not agree with Rav Ashi's proof?
(a) What does Rebbi Yehudah say with regard to placing two different Eruvin for the two days of Rosh Hashanah?
(b) Rebbi Yehudah also permits making a double-condition on the two days of Rosh Hashanah with regard to separating Ma'asros from a batch of Tevel. What exactly, does this entail?
(c) The Rabbanan do not agree with Rebbi Yehudah in either of the above cases. Why not?
(d) They also argue about an egg that is laid on Yom-Tov. What is the Machlokes there?
(a) Since the Rabbanan argue with Rebbi Eliezer above, and hold that Shabbos and Yom-Tov have the same Kedushah, why would they agree by the two days of Rosh Hashanah?
(b) In that case, who is the Tana who argues with Rebbi Yehudah (with regard to the two days of Rosh Hashanah) in our Mishnah, and who says that they both have one sanctity?
(c) What proof does Rebbi Yossi bring that the two days of Rosh Hashanah have one Kedushah?
(d) How do the Rabbanan refute that proof?
(a) Why did Rebbi Yehudah find it necessary to teach us that the two days of Rosh Hashanah are considered like one day with regard to Eruv, a basket of Tevel and an egg?
(a) Rebbi Yossi disagrees with Rebbi Yehudah - with regard to taking Ma'asros from a basket of Tevel on condition - on the two days of Rosh Hashanah. How does the Gemara initially quote Rebbi Yossi?
(b) Rav Sheshes declined to eat from the deer that was trapped on the first day of Yom-Tov, and Shechted on the second, because he took this statement literally. Rav Nachman and Rav Chisda however, did partake from it. Why does the Gemara reject the suggestion that what Rebbi Yossi was really coming to forbid was the second day of Rosh Hashanah in Galus, and not that of Yom-Tov Sheni shel Galuyos?
(c) How does the Gemara explain Rebbi Yossi's statement in light of Rav Nachman and Rav Chisda's actions?
(d) Why did Rav Sheshes subsequently ask Rabah bar Shmuel not to tell Rav Nachman and Rav Chisda what he had learnt from Rav?
(a) Rav Ashi has a different version of the story with the deer. What happened according to him?
(b) What will Rav Sheshes now hold in the original case (when the deer was trapped on the first day)?
(c) So why did Rav Sheshes request from Rabah bar Shmuel not to tell Rav Nachman and Rav Chisda what he had learnt from Rav?
(d) What is the basis of the above Machlokes, according to Rav Ashi?
