Ask A Question on the daf
Previous dafBeitzah 34
1) MAKING A NEW FLAME
(a) Question: Why is this prohibited?
2) HEATING ROOF TILES TO FRY UPON
(b) Answer: It is considered Molid on YomTov.
(a) Question: This should be permitted (a food need)!?
3) A RELATED MISHNAH FROM CHULIN
(b) Answer (Rabah b.b. Chanah citing R. Yochanan): We are
speaking of new tiles which may not withstand the heat
(or, they are thus hardened into service).
(a) One may slaughter a bird which survived 24 hours after
4) PARTAKING IN THE PROHIBITION OF BISHUL
(b) To be prohibited (Risuk Eivarim), the animal must also
be unable to stand up (Mefarcheses).
(c) If one slaughtered such an animal without waiting, the
animal must be examined for Risuk Eivarim to be
permitted, and it must also survive 24 hours (otherwise
its death renders it Risuk Eivarim, even if the
examination reveals no defect).
(d) Question (R. Yirmiyah): Is one permitted to slaughter
such a bird on YomTov (given that he may discover that
it has Risuk Eivarim, and the Shechitah will then have
been in vain (unlike other animals which are presumed
to be Kosher, even before the customary examination).
(e) Answer (R. Zeira): From our Mishnah (which prohibits
the heating of tiles on YomTov, because they need to be
tested) we see that it is not permitted.
(f) (R. Yirmiyah) The prohibition of tiles is owing to the
other reason (Tzarich l'chasman) and thus tiles cannot
be compared to the Mishnah in Chulin.
(a) Question: There appears to be a contradiction in the
Beraisos dealing with partial acts of Bishul!?
5) NEW KEILIM
1. One Beraisa teaches that if one person lights the
flame, another places wood, a third places the pot
on the stove, and a fourth pours in the water, yet
another adds spices and another stirs, they are
all Chayav (on Shabbos).
(b) Answer: The first Beraisa speaks when the first person
lit the flame whereas the second Beraisa speaks when
the last one lit the flame.
2. Another Beraisa teaches that only the last one is
(c) Question: What Melachah is done by the one who placed
the pot on the stove?
(d) Answer (Resh Lakish): The pot is a new one, and heating
it strengthens it akin to the tiles discussed above.
(a) One may move an oven on Shabbos (since it has use like
other Keilim) but one may not (even on YomTov) smear it
with oil or rub it with a cloth.
6) PROCESSING FOOD ON YOMTOV
(b) Cooling the oven with cold water is forbidden if it is
done to strengthen it, and permitted if it is to
prevent the bread from getting burned.
(a) One may boil the head or feet of a bird in boiling
water (in order to remove the hair) on YomTov but one
may not smear them with lime or earth (as would a
tanner) nor remove the hair with scissors (it looks as
if he is doing this for the hair).
7) MISHNAH: DECLARING ONE'S INTENT TO USE THE MUKTZEH
(b) One may not cut the leaves off vegetables with the
clippers with which one usually cuts them from the
ground (it appears a though he cut them from the ground
(c) One may prepare even those vegetables whose preparation
entails a lot of effort and one may heat up and cook (a
large amount of food) in a Purni or in a large kettle
since that is what is needed.
(d) One may not, however, use a new Purni since it might
crack from the heat (and one will have undertaken a lot
of trouble in vain).
(e) One may not fan the flames of a fire using bellows
since it looks like a professional job, but one may fan
the flames by blowing through a tube.
(f) One may not prepare or repair a spit for roasting.
(g) One may not break up a bamboo into strips to use as a
base for frying (Tikun Keli) but one may bit open a nut
wrapped in a cloth, even if there is a chance that the
cloth will tear.
(a) (R. Eliezer) One may stand by a Muktzah on Erev Shabbos
during Shemitah (when Ma'aser does not apply) and
verbally designate parts of it for use.
(b) (Chachamim) Verbal designation is not sufficient (one
must mark the fruit that he intends to use on YomTov)
because there is no Bereirah.
8) THAT WHICH IS KOVE'A FOOD AS BEING MA'ASER LIABLE
(a) Figs which children put away on Erev Shabbos and then
forgot about them are forbidden on Motzei Shabbos until
Ma'aser is taken (the effect of their being designated
as food for Shabbos).
9) SUPPORTING R. NACHMAN'S TEACHING FROM THE TANA'IM
(b) Figs which were put out in one's Chatzer to dry, his
family may eat them casually without having to separate
Ma'asros (a Chatzer is only Kove'a fruit for Ma'asros
if it is ready to eat not those put out to dry).
(c) Question (Rava): Does Shabbos causes Muktzah (which is
not yet completed) to become Kavu'a?
(d) Answer (R. Nachman): Shabbos is Kove'a.
(e) Question (Rav): Shabbos should be no stronger (as a
Kove'a) than a Chatzer (which is only Kove'a that which
is ready to eat)!?
(f) Answer (R. Nachman): We have a tradition that Shabbos
is Kove'a whether the food is, or is not, ready to eat.
(a) (Mar Zutra b.R. Nachman) Our Mishnah supports my
father's teaching since R. Eliezer permits verbal
designation on Erev Shabbos during Shemitah, implying
that, on any other year of the cycle, verbal
designation would not help (which indicates that
Shabbos is Kove'a even by something, like the Muktzeh,
which has not yet reached the stage of Ma'aser).
(b) We refute this proof by asserting that it is not
Shabbos that fixes there, but the verbal designation
that he made.
(c) Question: Then why does the Tana need to mention
Shabbos (the same will apply on a weekday)?
(d) Answer: The Tana teaches us the additional Chidush that
Tevel is Muchan on Shabbos (since Min HaTorah there is
no Isur of separating Ma'asros on Shabbos and YomTov,
it is technically Muchan).
