four Amos required?
(b) How do we substantiate Rav Nachman's distinction?
(c) According to Rav Chiya B'rei de'Rav Ivya's text in our Mishnah, the

What is his version of our Mishnah?
(a) We conclude the first group of prohibitions listed in our Mishnah ('Bor
Samuch le'Boro ... ') with 've'Sad be'Sid', and we ask whether it should not
perhaps read 'O Sad be'Sid'.
How do we attempt to resolve the She'eilah,
based on the second group of prohibitions ('es ha'Geffes ... ')?
(b) How do refute this proof? Why might the Tana state 'O Sad be'Sid' in the
Reisha too, and still list them as two sets?
(c) We cite the Beraisa where Rebbi Yehudah requires both neighbors to dig
their pits in 'Sela ha'Ba be'Yadayim' three Tefachim from the border and to
cement them with lime.

(d) How do we refute this proof, too?
(a) We learned in a Mishnah in Shabbos 'Ein Tomnin Lo be'Geffes, ve'Lo
be'Zevel, ve'Lo be'Melach, ve'Lo be'Sid, ve'Lo be'Chol'.
What is the
glaring discrepancy between that Mishnah and ours?

How does this Beraisa pose a Kashya on Rav Yosef's answer? What
did Rav Yosef say?
(c) Abaye therefore answers 'Yagid Alav Re'o'.
What does he mean by that?
(d) How does Rava refute Abaye's answer?
(a) How does Rava finally answer the Kashya.
Why does the Tana ...
(b) How do we reconcile this with Rebbi Oshaya, who forbids Reuven to place
his sand within three Tefachim of Shimon's wall?
- ... there (by Hatmanah) omit rocks'?
- ... here (by damages) omit sand?
(c) Our Tana does not find it necessary to insert wet sand however, since he
has already included a stream of water.
How do we then account for his
insertion of a laundry-pit, despite his already having mentioned a stream of
(d) Why would we not have known ...
- ... a laundry-pit from a stream of water?
- ... a stream of water from a laundry-pit?
(a) We learned in our Mishnah that Reuven must distance his seeds and his
plow at least three Tefachim from Shimon's wall.
Answers to questions
Why does the Tana need to
(b) But have we not already learned that watering is harmful to a wall, so
why does he need to mention plowing at all, seeing as trees require
watering? What do we learn from the Pasuk in Eikev "li'Metar ha'Shamayim
- ... seeds, seeing as someone who seeds will inevitably plow?
- ... plowing, seeing as this is followed by seeding, which he has already mentioned?
(a) The Mishnah in Kil'ayim forbids seeding the area directly above a
replanted branch of an attached vine.
What does the Tana of the Beraisa
comment on this Mishnah?
(b) Why must the Tana be speaking about a solitary vine (or even up to four
(c) Clearly then, seeds grow upwards and not sideways.
How does Rebbi
Chaga quoting Rebbi Yossi explain our Mishnah, which requires a distance of
three Tefachim between Reuven's seeds and Shimon's wall?
(a) How does Rabah bar Rav Huna learn from the Pasuk in Melachim
"ve'Hichrati le'Achav Mashtin ba'Kir ... "?
(b) Then how does he explain our Mishnah 've'es Mei Raglayim min ha'Kosel
(c) On what basis is Rabah bar Rav Huna proved wrong?
(d) What distinction does the Beraisa make between a wall of bricks and a
wall of stones?
(e) How do we then explain the Pasuk in Melachim? What does Mashtin ba'Kir'
(a) What does Rav Tuvi bar Kisna Amar Shmuel mean when he says 'Rakik Eino
(b) Does this mean that a thick loaf does diminish the space?
(c) Seeing as anything that is subject to Tum'ah does not prevent Tum'ah
from passing through, what is the Chidush?
(a) We ask on Shmuel from a Beraisa.
What does the Tana say about a box
full of straw or a barrel full of dried-figs which is lying on a window-sill
that divides between a room in which there is a corpse and another room?
Under what conditions will the straw or the figs prevent the Tum'ah from
passing into the second room?
(b) How can the straw prevent the Tum'ah from passing through under any
circumstances, seeing as it is fit ...
(c) But surely it is fit to fuel a big fire?
- ... to be fed to his animals?
- ... for making cement?
- ... for fuel?
(d) And by the same token, how can the figs prevent the Tum'ah from passing
through, seeing as they are fit to eat?
(a) Why does the barrel itself (that contains the figs) not prevent the
Tum'ah from passing through, despite the fact that the outside of an
earthenware barrel is not subject to Tum'ah and is therefore Chotzetz before
Answers to questions
