SUKAH 16 - Dedicated by Mr. A. Neff of New Rochelle, NY
1) PARTS OF A BED BEING MEKABEL TUMAH
(a) Question: In what Mishnah do we find the position of R.
Chanan citing Rebbi?
2) WORN OUT KEILIM
(b) Answer: It is a qualification of Chachamim in the Mishnah in
Keilim dealing with the Tumah and Taharah of parts of a bed.
1. (R. Eliezer) Only a complete bed is subject to Tumah.
2. (Chachamim) Sections of it can become Tamei (and Tahor)
3. Question: In what manner will parts be Tameh according
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.
(a) Question: What are the worn out Keilim which R. Ami b.
Tivyumi referred to as being S'chach Pasul?
3) A SUKAH CUT FROM WITHIN A HAYSTACK
(b) Answer: Clothes of less than the minimum size garment (3x3
(c) The Beraisa which invalidates the worn out grass mats from
being S'chach supports R. Ami b. Tivyumi (parenthetically, a
large mat which was made as S'chach is Kosher while a
smaller mat, made for sleeping, is not valid as S'chach.
(a) (R. Huna) The Pesul of the Mishnah is only if there is no
Tefach-deep (and 7x7 Tefachim large) hole.
4) MISHNAH: SPACE AT THE BOTTOM OR TOP OF THE WALLS
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 forbids it.
2. The resolution is the ruling of R. Huna, and the
Beraisa speaks of a case where a one-Tefach hole
(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 ruling).
(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 ground (Lavud).
5) MECHITZAH TELUYAH
(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 S'chach.
(c) (R. Yosi) A wall which is woven from the S'chach 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.
(a) Question: What is the basis for the Machlokes in the
(b) Answer: Whether a Mechitzah Teluyah (more than three
Tefachim off the ground) is considered a Mechitzah to permit
carrying (R. Yosi) or not (Tana Kama).
(c) The issue is the subject of the Mishnah in Eiruvin:
(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.
6) AN APPLICATION OF MECHITZAH TELUYAH
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 b.b. Chanah citing R. Yochanan) R. Yehudah above
holds like R. Yosi in our Mishnah (who permits a suspended
(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 Mavui with sheets
hanging from the posts to transport the Sefer Torah for use
(m) Question: How could they have brought out the sheets without
(n) Answer: They *found* sheets hanging, which did not reach the
ground, and they permitted their use, even though they were
a Mechitzah Teluyah.
(a) R. Chisda permits putting up a mat in between the ceiling
and the floor to form the wall of a Sukah.
7) MINIMUM LENGTH OF A SUKAH
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 established!?
2. We would be applying Lavud both at the top and at the
(c) Answer: We might not have known to apply Lavud twice.
(d) Question: But we see from the Beraisa (which requires that a
wall be seven-plus Tefachim) that we do *not* apply Lavud
(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 S'chach (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).
(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
(c) Answer: That the minimum size of a Sukah is seven Tefachim
(by seven Tefachim).
