(a) The Beraisa permits carrying inside a circle of a caravan encampment, provided the spaces between one camel and the next are not wide enough to fit a camel, and the spaces between one pile of saddles and the next are not wide enough to fit a pile of saddles etc. How does Rav Papa (who validates 'Parutz ke'Omed') explain this Beraisa?

(b) Why is a space of three Tefachim considered a breach (by sections of a wall that are less than three Tefachim), and less than that, not?

(c) What is the difference between the following cases: 1. A wall whose sections are less than three Tefachim; 2. A wall whose sections are between three and four Tefachim; 3. A wall whose sections are between four Tefachim and ten Amos; 4. A wall which contains a breach of more than ten Amos?

(d) Why should there be a difference between a breach of ten Amos and one of more than ten Amos?

(a) When will even a breach of more than ten Amos be permitted?

(b) To which area of Halachah is the above Beraisa related?

(c) How does Rav Papa explain the phrase (written with regard to the Din of between three and four Tefachim) 'u'Bilevad she'Lo Yehei Bein Zeh la'Zeh ke'Milu'o'?

(d) How does the Gemara prove this answer wording of the following case (of between four Tefachim and ten Amos)?

(a) According to Rav Papa, why does the Beraisa continue 've'Im Hayah *Omed Merubah al ha'Parutz*, Af Keneged ha'Parutz Mutar'? Why did it not say 've'Im Hayah Omed ke'Parutz, Mutar'?

(b) According to Rav Huna Brei de'Rav Yehoshua, why, in the Reisha, does the Beraisa say 've'Im Hayah *Parutz Merubeh al ha'Omed*, ... , Keneged ha'Parutz Asur'? Why did it not write 'Parutz ke'Omed, Asur'?

(c) According to Rav Huna Brei de'Rav Yehoshua, why does the Tana not combine the Din of a wall that is *less* than three Tefachim wall with one that is three Tefachim, since, in both cases, a breach of exactly three Tefachim will negate the wall?

4)

(a) According to Abaye, the Reisha of the Beraisa (which specifies Levud up to three Tefachim) follows the opinion of the Rabbanan. How does he then explain the Seifa, which makes a distinction between a wall of less than four Tefachim and one of four Tefachim (which seems to follow the opinion of Raban Shimon ben Gamliel - but in any event not the Rabbanan - see Tosfos DH 'Eima')?

(b) Rava establishes the Seifa like Raban Shimon ben Gamliel. How does he then explain the Reisha, which holds of Levud only up to *three* Tefachim and not *four*?

(c) Why do we rule like Rav Papa, in spite of the Beraisa, which explicitly requires 'Omed Merubeh al ha'Parutz'?

(a) How does one enclose an area with three ropes, to permit carrying inside it?

(b) That is a Mechitzas Arev. How does one arrange a Mechitzas Shesi?

(c) According to the Chachamim, although this Mishnah is a continuation of the Mishnah of an encampment, it nevertheless applies anywhere.
What does Rebbi Yehudah say about that?

(d) What does Rebbi Yossi b'Rebbi Yehudah hold?

(a) Rav Hamnuna asks whether Omed Merubeh al ha'Parutz (which is effective by a Mechitzas Shesi) is effective by a Mechitzas Arev - or whether a Mechitzas Arev must be completely closed. Why is there no proof from our Mishnah, which permits a Mechitzas Arev consisting of three ropes?

(b) The Gemara tries to resolve the Sha'aleh fact that the Mishnah permits only three ropes with a total thickness of one Tefach, which are three Tefachim apart. Why does it not permit three thin ropes including two spaces of just under three Tefachim, and the third space of just under *four*? How would this resolve our Sha'aleh?

(c) The Gemara rejects this proof on the grounds that, wherever the wider space was situated, there would be a problem. Why could the wider space not be ...

1. ... at the bottom?
2. ... at the top?
3. ... in the middle?

(a) The Gemara establishes Rav Hamnuna's Sha'aleh by a mat of seven Tefachim plus, in which three Tefachim had been cut out.
Where were the remaining four Tefachim plus, and how was the mat subsequently placed?

(b) According to Rav Ashi, the Sha'aleh concerns a Mechitzah Teluyah.
What, according to him, is Rav Hamnuna's Sha'aleh?

(c) What is the Gemara's conclusion?

(a) Rebbi Yehudah confines a Mechitzah of Shesi or Arev to an encampment. Does this mean that he totally rules out such a Mechitzah unless it is for an encampment?

(b) Rav Nachman initially made this distinction according to Rebbi Yossi b'Rebbi Yehudah, with regard to an encampment.
What does Rebbi Yossi b'Rebbi Yehudah say there? In which point does he argue with his father?

(c) What do the Chachamim of Rebbi Yossi b'Rebbi Yehudah hold?

(a) Rav Nachman quoting Shmuel, permits one Beis Sasayim (two Sa'ah) for one or for two people, and three for *three*.
What problem does Rav Nachman have with his Rebbi's statement?

(b) How does he amend it?

(c) Why is he not concerned that Shmuel nevertheless rules like Rebbi Yossi b'Rebbi Yehudah by one or two people?
