POINT BY POINT OUTLINE
Prepared by Rabbi Ephraim Becker
of Kollel Iyun Hadaf, Yerushalayim
1) PARTS OF A BED BEING "MEKABEL" "TUM'AH"
(a) Question: In what Mishnah do we find the
position of R. Chanan citing Rebbi?
(b) Answer: It is a qualification of Chachamim in
the Mishnah in Kelim dealing with the Tum'ah
and Taharah of parts of a bed.
1. (R. Eliezer): Only a complete bed is
subject to Tum'ah.
2. (Chachamim): Sections of it can become
Tamei (and Tahor) independently.
3. Question: In what manner will parts be
Tameh according to Chachamim?
4. Answer (R. Chanan citing Rebbi): Such as
one length of bed with its two legs, or
one width with its two legs.
i. Question: What is that good for?
ii. Answer: One can attach ropes to it
and then lean it against the wall and
sleep on it.
2) WORN OUT "KELIM"
(a) Question: What are the worn out Kelim which R.
Ami b. Tivyumi referred to as being Sechach
(b) Answer: Clothes of less than the minimum size
garment (3x3 Etzba'os).
(c) The Beraisa which invalidates the worn out
grass mats from being Sechach supports R. Ami
b. Tivyumi (parenthetically, a large mat which
was made as Sechach is Kosher while a smaller
mat, made for sleeping, is not valid as
3) A SUKAH CUT FROM WITHIN A HAYSTACK
(a) (R. Huna): The Pesul of the Mishnah is only if
there is no Tefach-deep (and 7x7 Tefachim
1. If there already is such a hole in the
haystack, and Ohel already exists for the
entire area of the Sukah.
(b) This ruling is supported by being the
resolution to a contradiction between our
Mishnah and a Beraisa.
2. It is then permitted to extend the height
of the walls from one Tefach to ten.
1. One Beraisa permits a Sukah cut from
within a haystack, while our Mishnah
(c) Others learn the ruling of R. Huna as having
been taught in order to resolve this
contradiction (and not having the contradiction
being brought as a support to his prior
2. The resolution is the ruling of R. Huna,
and the Beraisa speaks of a case where a
one-Tefach hole already exists.
4) "MISHNAH:" SPACE AT THE BOTTOM OR TOP OF THE WALLS
(a) (Tana Kama): A wall of a Sukah which is woven
from the top down is Kosher only if it reaches
to within at least three Tefachim from the
(b) A wall which begins from the ground is Kosher
as long as it reaches a height of ten Tefachim,
even though it does not reach within three
Tefachim of the Sechach.
(c) (R. Yosi): A wall which is woven from the
Sechach down, for at least 10 Tefachim, is
Kosher, even if it ends more than three
Tefachim from the ground, just like a wall
built from the bottom up.
5) "MECHITZAH TELUYAH"
(a) Question: What is the basis for the Machlokes
in the Mishnah?
(b) Answer: Whether a Mechitzah Teluyah (more than
three Tefachim off the ground) is considered a
Mechitzah to permit carrying (R. Yosi) or not
(c) The issue is the subject of the Mishnah in
(d) (Tana Kama): The residents of adjoining
courtyards may draw water from a shared well,
provided they made a partition for this purpose
(not relying on the property divider).
1. The partition must be 10 Tefachim tall.
(e) (R. Shimon b. Gamliel): The matter is subject
to a Machlokes Beis Hillel and Beis Shamai.
2. It may extend down to the water or only
into the lip of the well, as long as it is
built inside the well.
1. The opinion of the Tana Kama is that of
Beis Shamai while according to Beis
Hillel, the wall must extend close to the
level of the water.
(f) (R. Yehudah): The wall of the courtyard may
fill that role.
2. Tosfos DH Beis Shamai reverses the
opinions of Beis Shamai and Beis Hillel.
(g) (Rabah bar bar Chanah citing R. Yochanan): R.
Yehudah above holds like R. Yosi in our Mishnah
(who permits a suspended Mechitzah).
(h) In fact though, R. Yehudah does not hold like
R. Yosi, nor does R. Yosi hold like R. Yehudah.
1. R. Yehudah may only apply his lenient
ruling by Eruv (d'Rabanan, from one Reshus
ha'Yachid to another), but not by Sukah,
which requires a Mechitzah d'Oraysa.
(i) Question: But if R. Yosi concedes that a
Mechitzah Teluyah does not work on Shabbos,
then on what basis did they permit the incident
in his town, Tzipori!?
2. R. Yosi may permit a Mechitzah Teluyah
only by Sukah (a Mitzvas Aseh) while R.
Yehudah permits it even by Shabbos
(largely a Chiyuv Sekilah).
(j) Answer: That was in the days of R. Yishmael,
the son of R. Yosi, who disagreed with his
father in this point.
(k) Question: What was that incident?
(l) Answer: They constructed a make-shift Mavoy
with sheets hanging from the posts to transport
the Sefer Torah for use on Shabbos.
(m) Question: How could they have brought out the
sheets without an Eruv!?
(n) Answer: They found sheets hanging, which did
not reach the ground, and they permitted their
use, even though they were a Mechitzah Teluyah.
6) AN APPLICATION OF "MECHITZAH TELUYAH"
(a) R. Chisda permits putting up a mat in between
the ceiling and the floor to form the wall of a
1. The smallest height for the mat (in a
minimum height Sukah) would be four
Tefachim and a bit.
(b) Question: But the law of Lavud is well
2. We would be applying Lavud both at the top
and at the bottom.
(c) Answer: We might not have known to apply Lavud
(d) Question: But we see from the Beraisa (which
requires that a wall be seven-plus Tefachim)
that we do not apply Lavud twice!?
(e) Answer: That Beraisa is speaking about a large
Sukah, taller than ten Tefachim where he hangs
the seven-plus Tefachim within three Tefachim
of the Sechach (Lavud).
(f) Question: Then what is the news of the Beraisa?
(g) Answer: The Mechitzah is allowed to hang down
to within any distance from the bottom
(Mechitzah Teluyah is permitted in a Sukah,
like R. Yosi).
7) MINIMUM LENGTH OF A SUKAH
(a) (R. Ami): It is permitted to place a mat or
beam of four-plus Tefachim within three
Tefachim of an existing wall (and adjacent to
it), to form the second wall of the Sukah.
(b) Question: What is the news of this teaching
(since Lavud is well established)?
(c) Answer: That the minimum size of a Sukah is
seven Tefachim (by seven Tefachim).
