BEITZAH 11-15 - Ari Kornfeld has generously sponsored the Dafyomi
publications for these Dafim, for the benefit of Klal Yisrael
1) EXCEPTIONS FROM SHATNES (cont'd)
(a) (R. Papa) Shoe soles are exempt from Shatnes (due to
their hardness they do not warm the wearer).
2) THE SPIKED SANDAL
(b) (Rava) Pouches for storing coins are exempt (they are
stiffened by the friction with the coins) while pouches
for storing seeds are liable.
(c) (R. Ashi) Both types of pouches are exempt since they
do not warm the person in the normal manner.
(a) Question: Why is this gift prohibited?
3) THE UNSTITCHED SHOE
(b) Answer: Owing to the tragic incident (Shabbos 60a).
(c) (Abaye) While they may not be worn on YomTov, they are
not Muktzeh (since otherwise the Mishnah would not need
to teach that they cannot be sent).
(a) Question: Is this prohibition not obvious!?
4) AN UNPOLISHED SHOE
(b) Answer: We might have permitted if the parts had been
(a) (R. Yehudah) A black shoe (even though it requires
polishing to smooth it) is permitted while a white (yet
undied shoe) is prohibited.
5) TEFILIN AS AN APPLICATION OF THE GENERAL RULE FOR SENDING
(b) (R. Yosi) The black shoe is also prohibited owing to
its need to be polished.
(c) Each Tana is speaking with reference to the practice in
1. In R. Yehudah's locale the flesh-side of the hide
is placed on the inside of the shoe (which then
does not need to be polished).
2. In R. Yosi's locale the flesh-side was out and
thus needed to be smoothed by polishing.
(a) (R. Sheshes) It is permitted to send Tefilin on YomTov.
6) WHILE ON THE SUBJECT OF TEFILIN
(b) Question (Abaye): But no benefit may be derived from
them on YomTov (and thus they fail the general rule of
(c) Answer (R. Sheshes): The rule permits anything from
which benefit may be derived, even on a weekday.
(a) (Abaye) One who is wearing Tefilin on his travels when
the sun set (on Erev Shabbos - Rashi, but see Tosfos)
covers the Tefilin until he reaches his home.
Hadran Alach Beitzah
(b) Similarly, one who is in the Beis Medrash learning when
Shabbos enters places his hand on his Tefilin until he
gets to his home.
(c) Question (R. Huna b.R. Ika): But we were taught that in
both cases he walks only to the nearest home!?
(d) Answer: That Beraisa is speaking where the nearest home
provides safety for the Tefilin.
(e) Question: But if the Tefilin would not be safe then
even if he were not wearing them he would be permitted
to don them in order to bring them to safety on Shabbos
(as in the Mishnah in Eruvin)!?
(f) Answer: The Mishnah permits donning them where their
present location does not provide protection even from
dogs, while Abaye is speaking where his present place
is safe from dogs but not from thieves.
1. Whereas we might have assumed that Jewish thieves
would not tamper with Tefilin (and thus they
should be left in their place even if he is
2. Abaye has taught that if he is wearing them, the
concern for the abuse of thieves is sufficient to
permit wearing them to safety (but not to put them
on if he is not wearing them).
1) MISHNAH: ERUV TAVSHILIN
(a) One may not cook on YomTov for Shabbos, but one may
cook for YomTov and eat the leftovers on Shabbos.
2) THE BASIS FOR ERUV TAVSHILIN
(b) To cook expressly for Shabbos one must cook a food (as
Eruv Tavshilin) before YomTov and rely on it to cook
further on YomTov for Shabbos.
1. (Beis Shamai) The Eruv requires two cooked foods.
(c) One must not (continue to) cook if the Eruv were eaten
or lost, unless a bit of the Eruv remains.
2. (Beis Hillel) One food is sufficient.
3. A fish fried with egg qualifies as two foods.
(a) Question: On what basis did Chazal institute Eruv
3) TORAH STUDY AND SIMCHAS YOMTOV
(b) Answer (Shmuel): They used the word Zachor as a hint to
remember that which we might forget (Shabbos, when
YomTov precedes it).
(c) Question: Why did they institute Eruv Tavshilin?
(d) Answer (Rava): To insure that a proper portion of food
be readied for Shabbos (and not all used for YomTov).
(e) Answer (R. Ashi): To remind the person that it is not
permitted to cook on YomTov for a weekday (since even
to cook for Shabbos requires an Eruv).
(f) Question: Why, according to Rava's reasoning, must the
Eruv be prepared before YomTov (it should be made
whenever the YomTov meal is being prepared in order to
protect the honor of Shabbos)?!
(g) Answer: It could be so, but we are afraid that one
might be negligent and not make an Eruv.
(h) (Beraisa, offering a different basis for the
institution of Eruv Tavshilin) They used the Pasuk Es
Asher Tofu Eifu...
1. (R. Elazar) These words indicate that one must
bake on the basis of that which was already baked,
and cook based on that which was previously
2. This then, is the allusion in the Pasuk to Eruv
(a) (Beraisa) R. Eliezer identified each group of those who
left his Derashah as being drawn by successively
smaller quantities of wine until he looked
disparagingly at those who simply left the Beis Medrash
4) THE PASUK IN NECHEMIAH (8:10)
(b) R. Eliezer assured the remaining students that he was
not angry with them, but at those who had left
(abandoning eternal matters to engage in temporal
ones), and he sent the remaining students home to enjoy
their meals, invoking the Pasuk in Nechemiah (8:10).
(c) Question: But Simchas YomTov is a Mitzvah (an eternal
(d) Answer: R. Eliezer was of the view that this Mitzvah is
optional (as he taught in the Beraisa that one may
fulfil Simchas YomTov with a day filled with feasting
or with Torah study).
(e) (R. Yehoshua) The YomTov day should be divided between
the two forms for Simchah.
(f) (R. Yochanan) They each resolve the Pesukim differently
(Atzeres LaShem in Devarim and Atzeres LaChem in
(a) Question: What is meant by sending portions l'Ein
5) ANOTHER TEACHING FROM THE SAME SOURCE
(b) Answer (R. Chisda): Send to he who did not make an Eruv
Tavshilin (and thus cannot prepare for Shabbos).
(c) Alternate Answer: To he who could not have prepared an
Eruv (but not to the negligent one who did not do so).
(d) Question: What is meant by Chedvas HaShem Hi Ma'uzchem?
(e) Answer (R. Yochanan citing R. Eliezer b.R. Shimon): One
may rely on HaShem to cover the debts incurred by
performing Simchas YomTov.
(a) (R. Yochanan citing R. Eliezer b.R. Shimon) One who
wishes to preserve his property should plant an Adar
(as alluded to in the Pasuk in Tehilim 93 or in the
name Adar itself) as supported by the Beraisa (that a
field with an Adar is not stolen and its fruits are
