Shabbos 85


(a) What do we learn from the Pasuk in Devarim "Lo Sasig Gevul Re'acha Asher Gavlu Rishonim"? What is the connection between this Pasuk and our Mishnah?

(b) Who are the Rishonim mentioned in the Pasuk?

(c) What method did they use to determine which land was good for planting which trees, and how is that inherent in their names - the Chori and the Chivi?

(d) What did Rav Acha bar Ya'akov mean when he explained that the name Chori is a hint 'she'Na'asu B'nei *Chorin* mi'Nichsehen'?

(a) 'Arugah Tochah Shishah - Chutz mi'Gevuleha'?
What does the statement mean?

(b) What Shiur does Rebbi Yehudah give for the width of the surrounding border?

(c) What is his source for this?

(a) Why does Rav establish our Mishnah in the case of one solitary patch not surrounded by other patches?

(b) Would it at all be possible to plant five different seeds in patches that were planted next to each other?

(c) Rav establishes our Mishnah 'be'Memale es ha'Keranos'.
What does this mean?

(d) How does Rashi's explanation of 'ha'Keranos' differ here from what he said in the Mishnah.

(a) What does the Gemara mean to ask with its next question 've'Liz'ra me'Abra'i, ve'Lo Limli mi'Gava'i'?

(b) What is the answer to this question?

Answers to questions



(a) What is the Heter of 'Rosh Tor'?

(b) How does the Gemara attempt to apply that Heter in our case?

(c) On what grounds is this suggestion rejected?

6) Shmuel disagrees with Rav. According to him, our Mishnah speaks about a patch surrounded by patches.
Why is he not concerned about the different species mixing when they grow?


(a) Who are the B'nei Ma'arva?

(b) What did the B'nei Ma'arva mean, when they asked: 'Hifki'a Telem Al Penei Kula, Mahu'?

(c) Rav Sheshes holds that a furrow *does* negate the Din of Arugah. Rav Asi holds that it does *not*. The Mishnah in Kil'ayim forbids single alternate rows of pumpkins and cucumbers.
Why is this not a proof for Rav Asi?

(d) Why then, are *two* alternate rows of pumpkins and cucumbers permitted?

(a) What advice does Rebbi Yochanan offer to anyone who wishes to fill his entire field with vegetables?

(b) When he says 'his entire field', is this to be taken literally - according to Amri de'Bei Rav Yanai?

(c) Rav Ashi *does* take Rebbi Yochanan literally.
How is this possible?

(d) How does Rebbi Yochanan explain the Beraisa, which specifies a *square* box, when describing an Arugah? Does this not imply that, if it is in the form of a circle, it is forbidden?

9) We have just described the advantage of a square patch over the circlular patch of Rebbi Yochanan.
What are the advantages of Rebbi Yochanan's circular patch over the square patch of our Mishnah?
