Sukah 17

SUKAH 17 - Dedicated by Seth and Sheila Jutan of Atlanta, Georgia, in memory of her grandfather, Mr. Bernie Slotin (Dov Ber ben Moshe Mordechai z'l), who passed away on Chol ha'Moed Pesach (18 Nisan 5759 - April 4, 1999).


(a) We have already learned that at the side of the Sukah, four Amos of *Pasul S'chach* invalidates the Sukah.
How much *empty space* will invalidate the Sukah at the side?

(b) Which explanation of Dofen Akumah does Rashi reject on account of this Halachah?

(c) The Tana gives three examples of Dofen Akumah. Having stated ...

1. ... the case of the broken ceiling of a house, why did he find it necessary to add that of the covered porch or passageway which surrounds a courtyard?
2. ... the previous two cases, why did he find it necessary to add the case of the Sukah with Pasul S'chach around the side?
(a) According to the Rabbanan de'Bei Rav, four Tefachim of Pasul S'chach will invalidate the Sukah *in the middle of the Sukah*.
What constitutes the middle of the Sukah?

(b) Rabah queried them from our Mishnah, which permits Pasul S'chach op to four Amos.
What did they reply in the name of Rav and Shmuel?

(c) How does Rabah attempt to disprove the Rabbanan de'Bei Rav from a Sukah with less than *four* Tefachim of Pasul S'chach and less than *three* of space, which is Kasher?

(d) What did they retort?

Answers to questions



(a) How does Rabah explain why, although his Kashya is *not* a Kashya on himself, it *is* a Kashya on them?

(b) Rabah vindicates himself on the grounds that according to him, it is a matter of Shiurim, and the Shiur of Pasul S'chach and that of space cannot combine because they are different. Abaye queries this from the case of a small Sukah.
What is his query?

(c) And how does Rabah answer that?

(a) The Mishnah in Keilim rules that the Shiur Tum'ah of cloth is three by three Tefachim, of sack, four by four, of leather, five by five, and of a mat made of platted reeds, six by six.
Which Tum'ah is the Tana referring to?

(b) Will any of these combine (if sewn together) to become subject to Tum'ah?

(c) Why do *they* combine to become Tamei, whereas in Rabah's case, they do *not*?

(d) In which case do all of the above materials have the same Shiur?

(a) In whose name is Rabah's statement quoted in the second Lashon? Who disagrees with him?

(b) How will Shmuel interpret the Mishnah, which *validates* a plank of four Tefachim?

(c) What is the problem from Rebbi Meir in the Beraisa, who maintains that two planks combine, with Rav, who learns in the second Lashon, that, in the middle of the Sukah, four Tefachim of S'chach Pasul invalidates the Sukah? Why is this a Kashya only on Rav, and not on Shmuel?

(d) How does Rav answer that?

6) In the Beraisa that we quoted above on Daf 14b, Rebbi Meir agrees that even by planks of four Tefachim, the Sukah is Kasher if one leaves the equivalent space which one fills in with S'chach. How will those who hold that a plank of four *Tefachim* will already invalidate a Sukah, explain that?
