SUKAH 21-25 - my brother Ari Kornfeld has generously sponsored one month of
Dafyomi publications for the benefit of Klal Yisrael
(a) If the S'chach is as thick as a house, is the Sukah Kasher?
(b) Does it make any difference whether one can see the stars through it or
(a) The Tana of our Mishnah invalidates a Sukah ha'Meduvleles. Rav describes
this a Sukah Aniyah (like the word 'Meduldeles' - poor).
What is a 'Sukah
(b) Shmuel interprets 'ha'Meduvleles' like 'ha'Mevulbeles'.
What does that
(c) The Tana of our Mishnah follows the Din of a Sukah ha'Meduvleles with
've'she'Tzilasah Merubah me'Chamasah'.
Is this a continuation of the
Reisha or is it an independent Halachah ...
- ... according to Rav?
- ... according to Shmuel?
(a) Abaye disqualifies Shmuel's 'Sukah ha'Meduvleles', should the top plank
be three Tefachim or more away from the one below. Rava declares it Kasher,
provided the top plank is at least one Tefach wide.
The Beraisa establishes the former case (d 1.) when the spaces and
consequently the top planks, were at least one Tefach wide.
Why is that?
(b) What is 'Chavot Rami' known as in connection with a wall?
(c) Rava proves his point from a Mishnah in Ohalos: If there are two rows of
planks, one on top of the other, with gaps between each plank: where would a
vessel have to be to become Tamei , if the Tum'ah (i.e. the piece of corpse)
(d) Where would the vessel have to be ... if the top planks, instead of
being directly above the lower planks, were above the spaces in between the
lower ones, if the Tum'ah was ...
- ... underneath one of the planks?
- ... on top of the lower plank?
- ... on top of the top plank?
- ... underneath any one of the planks?
- ... on top of any one of them?
What would be
the Din if they were not? How does Rava prove his point from there?
Answers to questions
(a) We already quoted the Beraisa (on 18a), which extends (through the Din
of 'Levud') a Koreh that stretches across the entrance of a Mavoy to within
three Tefachim of the opposite wall, or two Koros that do not quite meet in
the middle of the entrance, stopping short within three Tefachim of each
What does Raban Shimon ben Gamliel say? What does he hold with
regard to 'Levud'?
(b) What is the minimum width that two beams placed beside each other may be
in order to serve the Mavoy as a Koreh?
(c) Raban Shimon ben Gamliel is lenient in this point too.
What does he
say? How could the two beams be placed, even if they had a combined width of
less than one Tefach?
(a) If the two beams were of a different height, Rebbi Yossi b'Rebbi Yehudah
combines them, provided one is not higher than twenty Amos and the other one
lower than ten Tefachim.
What do we at first infer from Rebbi Yossi
b'Rebbi Yehudah's words? With which principle will we then permit the two
beams of different heights?
(b) How does that leave us with a Kashya on Rava's distinction between a
Tefach and less than a Tefach by Chavot Rami?
(c) How do we amend our inference to resolve this problem? How close must
the two beams be to be permitted, and which principle do we now apply in
order to permit them?
(a) Why do our Mishnah, which *validates* a Sukah with more *shade than
sunshine*, and the Mishnah at the beginning of the Masechta, which
*invalidates* a Sukah that has more *sunshine than shade*, appear to
contradict each other?
The Tana of our Mishnah validates a Sukah even if the S'chach is so thick
that the stars cannot be seen through it.
(b) How do we reconcile the two Mishnahs?
(c) What popular saying is contained in this answer?
How thick will the S'chach have
to be for Beis Shamai to invalidate the Sukah (though Beis Hillel disagree)?
(a) The Tana of our Mishnah validates a Sukah that is built on top of a
wagon or of a ship.
Why would we have thought otherwise? What is the
(b) What is the difference between the two above cases and a Sukah that is
built on top of a tree or on top of a camel, which is also Kasher? Why does
the Tana separate them?
(c) If entering a tree-Sukah is forbidden on Yom-tov, then what point is
there, in informing us that it is Kasher?
(d) Has one performed the Mitzvah of Sukah if one enters it on Yom-tov, in
spite of the prohibition?
(a) May one enter a Sukah on Yom-Tov ...
Answers to questions
1. ... if two walls of the Sukah are supported by trees which were extended
upwards by man-made walls, with the third wall man-made from the ground
(b) Is there any case when one would be permitted to enter a Sukah which was
partially supported by a tree?
2. ... if the two adjacent walls were completely man-made, and the third one
was supported by the tree?
(c) What is the binding principle in this matter?
