(a) What did Rav say about the Beraisa which says with regard to a Tzuras ha'Pesach that is wider than ten Amos: 'Ein Tzarich Lema'et'?

(b) Does an Amaltera rectify a Mavoy whose entrance is more than ten Amos wide?

(a) What did Rav Yosef deduce from Rav's stringency concerning a Tzuras ha'Pesach (see previous question), with regard to a Chatzer whose majority (of each of the four sides) consists of a series of Tzuros ha'Pesach?

(b) How does the Gemara refute Rav Yosef's proof, from Pasei Bira'os?

(c) The Beraisa reads 'Arba Defanos Halalu, *she'Ruban Pesachim va'Chalonos*, Mutar ... '? The Gemara changes the text. How does the new text read? Why does the Gemara find it necessary to change it?

3) What are 'Pischei Shima'i'?

What does Rebbi Yochanan hold?

(c) They could be arguing over a Tzuras ha'Pesach that is wider than ten Amos. What else might they be arguing about?

Answers to questions



(a) How do we reconcile Resh Lakish with another statement, in which, quoting Rebbi Yehudah b'Rebbi Chanina, he permits 'Pe'ah' by Kil'ayim, but not by Shabbos?

(b) In which two ways can we reconcile Rebbi Yochanan's statement *here* with with his own statement *there*, where he forbids Pe'ah, even by Kil'ayim?

(c) From where does Rebbi Yochanan know to differentiate between a Tzuras ha'Pesach that is ten Amos wide and one that is more than ten Amos wide - even by Kil'ayim?

(d) How did he know that Rebbi Yochanan ben Nuri was referring to a case when the cross-beam was fitted to the *side* of the side-posts, and not to the *top*?

(a) How strong must a Tzuras ha'Pesach (for Shabbos) be?

(b) Does a Tzuras ha'Pesach require a door?

(c) Does a Tzuras ha'Pesach require a Heker Tzir? What is a Heker Tzir?

(a) Who was Rav Gada, and what did he do?

(b) Why did the Resh Galusa's men lock him up?

(c) How long did he spend in goal?

(a) According to Rebbi Meir, an archway requires a Mezuzah; according to the Rabbanan, it does not. In which case do the Rabbanan agree with Rebbi Meir?

(b) In which cases does Rebbi Meir agree with the Rabbanan?

(c) In which case then do they argue, and what is the basis of their Machlokes?

(d) When Rabah bar Shmuel told this to Rav Sheshes, what did Rav Sheshes tell him, and why was that?

(a) According to the Tana Kama of our Mishnah, a Mavoy according to Beis Shamai, requires a Lechi and a Koreh; according to Beis Hillel, it only requires one or the other. What are the other two opinions (Rebbi Eliezer and a Talmid quoting Rebbi Yishmael) in this matter?

(b) How do we reconcile our Mishnah with Chananya and with his Tana Kama, who also require a door or a Tzuras ha'Pesach (respectively) - at the other end?

(c) What prompts the Gemara to suggest that, according to Beis Shamai, a Reshus ha'Yachid requires four walls - min ha'Torah (and Beis Hillel three)?

(d) What do Beis Shamai (and Beis Hillel) really hold?
