Ask A Question on the daf
Previous dafSukah 6
(a) Question: But (contrary to R. Chiya's teaching that Shiurim
[along with Chatzitzos and Mechitzos] are Halachah l'Moshe
MiSinai) we find that Shiurim are d'Oreisa!?
1. The Pasuk in Devarim (8:8) praises Eretz Yisrael for
its fruits (Eretz Chitah U'Se'orah VeGefen...).
(b) Answer: These do not present the Shiurim, they only provide
the basis for Asmachata, the Shiurim are, indeed, Halachah
2. The Pasuk is understood to list each food item in order
to instruct us regarding Shiurim.
i. Chitah- the time Shiur for becoming Tamei in a
house afflicted with Tzara'as (stated as the time
needed to eat a Peras) is made shorter owing
(among other things) to the bread being made of
wheat (and not barley, which takes longer to eat).
3. The implication from these derivations being that these
ii. Se'orah- the amount of human bone which would
create Tumah upon contact or being borne.
iii. Gefen- the measure of a Revi'is for a Nazir is
made using wine (which, due to its viscosity, will
spill out less than water under the same
iv. Te'eina- the Shiur of food for Hotza'as Shabbos.
v. Rimon- the Shiur of a breach for Taharas Keilim.
vi. Zeis Shemen- All of the Land's Shiurim use a
(1) Question: *All* Shiurim!?
vii. Devash- the plump date is the Shiur for eating on
(2) Answer: We mean the great majority.
(a) Question: How could R. Chiya have taught that Chatzitzos are
Halachah l'Moshe MiSinai given that they are derived from
the Pasuk V'Rachatz BaMayim!
(b) Answer: We need the Halachah l'Moshe MiSinai for the
Chatzitzah of hair (as taught by Rabah b.b. Chanah).
1. One hair (tied to itself) is a Chatzitzah.
(c) Question: But hairs are also derived from the Pasuk!?
2. Three hairs (tied together) are not a Chatzitzah.
3. Two hairs (tied together) are questionable.
1. The Derashah is made from Es Besaro.
(d) Answer: The Halachah l'Moshe MiSinai teaches us Chatzitzah
as taught by R. Yitzhok (Rov and Makpid).
2. This comes to include that which is Tafel to the body,
3) MECHITZOS TEN TEFACHIM
1. Mi'd'Oreisa (meaning from the Halachah l'Moshe
MiSinai), only Rov with Makpid create a Chatzitzah (not
2. Chachamim added Rov without Makpid and Makpid without
Rov as Chatzitzos.
3. Question: Why did they not add not Makpid without Rov
(Mi'ut v'Eino Makpid) lest it be confused with Makpid
4. Answer: That would be a Gezeirah l'Gezeirah.
(a) R. Chiya taught that it is Halachah l'Moshe MiSinai.
4) THE PESUL OF LESS THAN THREE DEFANOS (WALLS)
(b) Question: Unlike R. Yehudah (who needs the Halachah l'Moshe
MiSinai since his five-Tefach Amah does not let him learn
Mechitzos from the Aron plus Keruvim), why would we need a
Halachah l'Moshe MiSinai according to R. Meir?
(c) Answer: The Halachah l'Moshe MiSinai is needed to teach the
Halachos of Gud (Asik and Achis- Halachically drawing the
Mechitzah up or down), Lavud, and Dofen Akumah.
(a) (Tana Kama) There must be two proper walls, at right angles
to each other, and a third may be only a Tefach.
(b) (R. Shimon) There must be three proper walls and the fourth
may be a Tefach.
(c) Question: What is their Machlokes?
(d) Answer: Chachamim give priority to the way the word is
written in the Torah (Eim LaMasores) while R. Shimon gives
precedence to the manner in which the word is read (Eim
1. (Chachamim) The word BaSukos is written defectively
twice (no Vavin, as though singular) and fully once
(two Vavin, plural) for a total of four walls.
(e) Alternate Answer: While all hold Eim LaMikrah, they argue
whether an additional references must be deleted (Chachamim)
to teach the Mitzvah of S'chach itself, or not (R. Shimon).
i. One reference is needed for the actual Mitzvah of
2. (R. Shimon) All three occasions of BaSukos are read the
same way, as plural, giving us six walls.
ii. This leaves three, two of which must be proper,
and the third may be a Tefach owing to the
Halachah l'Moshe MiSinai.
i. One reference is subtracted for the actual Mitzvah
of Sukah, leaving four Mechitzos.
ii. Three of which must be proper, and the Halachah
l'Moshe MiSinai allows the fourth to be a Tefach.
(f) Alternate Answer: While all hold Eim LaMasores, they argue
over whether the Halachah l'Moshe MiSinai is coming to allow
one to diminish the third wall to a Tefach (Chachamim) or to
require the addition of a Tefach of a fourth wall to the
stated three (R. Shimon).
(g) Alternate Answer: While all agree that the Halachah l'Moshe
MiSinai comes to diminish the wall, and while all agree to
Eim LaMasores, and they are arguing over whether we are to
be Dorshin Techilos (R. Shimon-inferring from the opening
reference, giving us four walls) or not (Chachamim).
(h) Alternate Answer (R. Masna): R. Shimon derives his position
(of four walls) from the Pasuk in Yeshayah (4:6) which
speaks of a Sukah as protection from the air-stream (only
possible with four walls).
