Previous daf

1) The Din in all of the combinations of two Sukos, one above the other dealt with in the previous Beraisa, is obvious, except for one.
Which one? What is the Chidush?

2)

(a) According to Rav Huna, the distance between one Sukah and the other for it to be considered one Sukah above the other (and not just one Sukah) is *three* Tefachim.
What is his source for this?

(b) What does the Mishnah in Ohalos mean when it says 'Tefach al Tefach be'Rum Tefach ...

1. ... Meivi es ha'Tum'ah'?
2. ... Chotzetz Bif'nei ha'Tum'ah'?

(c) Rav Chisda and Rabah Rav Huna give the distance between the two Sukos as *four* Tefachim.
What is their reason?

(d) What does Shmuel hold?

(a) Rebbi Yehudah disagrees with the Tana Kama in our Mishnah who invalidates a Sukah that is beneath another; *he* says that if there is no- one living in the top Sukah, the bottom Sukah is Kasher.
Why can we not explain this literally?

(b) So we explain the Mishnah to mean, not that there is nobody living in the top Sukah, but that it is not *fit* to live in. What do we currently take this to mean, and why does that present a Kashya on Shmuel?

(c) In Eretz Yisrael they concluded that, if Rebbi Yehudah was referring to two Sukos that were less than ten Tefachim apart, even the Rabbanan would agree that the bottom Sukah was Kasher.
What then, *is* Rebbi Yehudah referring to?

(d) If the dividing S'chach cannot hold the blankets etc., of the top resident, why do the Rabbanan invalidate the bottom Sukah?

(a) If one spreads a sheet across the Sukah, either on top, to protect the Sukah from the sun, or underneath, to protect it from the droppings of S'chach, the Sukah is Pasul.
Why?

(b) Why will sleeping underneath a four-poster bed over which a sheet has been draped, not be forbidden *for the same reason*?

(c) May one sleep underneath a four-poster bed over which a sheet has been draped?

(d) One may however, spread a sheet over 'Naklitei ha'Mitah'.
What are Naklitei ha'Mitah? Why is this permitted?

(a) Why does a canvass with pictures spread across the ceiling to beautify the Sukah, not invalidate it?

(b) Why did Rav Chisda need to tell us this? Why is it not obvious from the fact that the Mishnah speaks about protecting the Sukah from the sun or from the droppings, and not about beautifying it?

(a) The Beraisa forbids taking down and using the ornaments that are hanging in the Sukah until after Shemini Atzeres, and it lists various types of colored hangings, nuts, and fruits etc. as examples of this.
Why is this prohibited (see Tosfos 9a DH 'Minayin')?

(b) Under which condition will it be permitted to take them down and use them?

(c) Why is there no proof from this Beraisa that ornamental hangings that are spread across the ceiling do not invalidate the Sukah?

7)

(a) Do ornaments affect the height of the Sukah ...

1. ... when they are suspended from the S'chach (i.e. to be Machshir it if it is more than twenty Amos high, or to render it Pasul if it is exactly ten Tefachim high?
2. ... if they are attached to the wall of a Sukah that is exactly seven by seven Tefachim wide?

(b) Why did Rav Ashi instruct Menimin to remove the wet shirt from the roof of the Sukah, where he had hung it up to dry?

(c) Who was Menimin?

(d) Why would it not be obvious to all and sundry from the fact that they were wet, that the shirt was hung up *to dry*, and not to *cover* the Sukah?

(a) According to Rav Nachman, ornaments that are dangling to below four Tefachim, do not invalidate the Sukah.
What do Rav Chisda and Rabah bar Rav Huna say?

(b) Why did Rav Chisda and Rabah bar Rav Huna not protest when Rav Nachman arranged for them to sleep in the Resh Gelusa's Sukah, where ornaments were dangling to below four Tefachim?

(c) What was Rav Nachman doing organizing the guests in the Resh Galusa's Sukah?

(a) How do we reconcile Rav Yehudah Amar Shmuel, who permits sleeping in a Kilas Chasanim (a type of four poster bed), provided the posts over which the sheet is draped are less than ten Tefachim high, with the Beraisa, which forbids someone to sleep in a four-poster bed in a Sukah which has a sheet spread across its posts?

(b) How will we then establish the Mishnah in ha'Yashen, which renders not Yotze someone who sleeps underneath a bed on Sukos?

(c) What can we infer from the Beraisa, which after probihiting sleeping under a sheet that is draped over a four-poster bed, permits sleeping under a sheet that is draped over a two-poster bed, provided it is less than ten Tefachim high?

(d) Then how do we reconcile this with the Rav Yehudah's Kilas Chasanim, which is Kasher as long as it is less than ten Tefachim high?

11)

(a) Based on the previous Halachah, Shmuel rules that someone who is sleeping naked in a Kilas Chasanim may stick his head outside the sheet and recite the Shema.
Why is that? How high is the sheet?

(b) What would Shmuel rule in the same case, if he was sleeping in a four- poster bed?

(c) And how will he explain the Beraisa which forbids it even in a Kilas Chasanim?

(d) How do we prove this answer from the Seifa of the Beraisa, regarding a similar case regarding the recital of Keri'as Shema in the house? Will this Din apply to a house that is less than ten Tefachim high?
