Ask A Question on the daf
Previous daf Chulin 126
1) COVERED "TUM'AH"
(a) (Seifa): If the cupboard is in the doorway, facing out:
2) "TUM'OS" THAT ARE "TAMEI" IN TWO WAYS
1. If Tum'ah is in the cupboard, the house is Tahor; if
Tum'ah is in the house, the cupboard is Tahor.
(b) (Beraisa - R. Yosi): It is Tahor.
(c) Question: Which teaching of Chachamim does R. Yosi
1. He cannot discuss the Seifa (as it is), for
Chachamim are also Metaher!
(d) Answer: Rather, he heard that Chachamim are Metamei in
two cases, and argues about both:
1. When it is the way of Tum'ah to leave (the Reisha),
R. Yosi is Metaher, for perhaps a complete k'Zayis
will not leave at once, or it might be burned in its
(e) Contradiction: Elsewhere, R. Yosi says that covered
Tum'ah goes through the covering!
2. In the Seifa, Chachamim hold that a covered Tum'ah
pierces through; R. Yosi says that it does not.
(f) (Mishnah - R. Meir): If a dog ate flesh of a Mes and died
(within three days) and is resting on the threshold, it
brings the Tum'ah into the house only if the opening of
its neck is [at least] a Tefach [by a Tefach]).
1. R. Yosi says, we look: if it (the Tum'ah inside the
dog) is inside the doorway (or house), the house is
Tamei; if it is outside the doorway, the house is
(g) Answer (Rava): No - R. Yosi says we look at the
*interior* of [what brings] the Tum'ah (i.e. the neck, if
it is a Tefach by a Tefach); he argues with R. Meir in
2. R. Elazar says, if the dog's mouth is in the house
(and the Tum'ah and rectum are out), the house is
Tamei; if its mouth is out (and the rectum is in),
the house is Tahor.
3. R. Yehudah ben Beseira says, in either case the
house is Tamei.
4. Summation of question - suggestion: R. Yosi refers
to the case when the neck is not a Tefach thick -
even though the Tum'ah is covered, it pierces
through and is Metamei the house (if it is inside
1. R. Meir says that if the neck is a Tefach, it brings
Tum'ah; R. Yosi says the interior must be a Tefach;
(h) Rav Acha brei d'Rava's text of the Beraisa explicitly
says "R. Yosi says we look at the hollow in which the
2. R. Meir holds that the roof above the entire
threshold brings Tum'ah to the house; R. Yehudah
says only the part inside the doorway.
(a) Question: Who is the Tana that argues with R. Yosi and
says that towering is not called touching?
(b) Answer: It is R. Shimon.
3) "SHERETZ" EGGS
1. (Beraisa - R. Shimon): There are three Tum'os of
Mes, each of which is Metamei in exactly two of the
three possible ways:
(c) (Mishnah): The femur of a Neveilah or Sheretz...
i. A spoon of Rekev has Tum'as Ohel and Masa, not
ii. A bone the size of a barley seed has Tum'as
Maga and Masa, not Ohel;
iii. Golel and Dofek (Rashi - the cover of a coffin
and its support) have Tum'as Ohel and Maga, not
(d) (Beraisa): "Nivlaso [is Tamei]" - not a femur without a
1. Suggestion: Perhaps it is Tahor even if it has a
(e) Question (R. Oshiya): If one planned to puncture the
femur, but did not, is it Tamei?
2. Rejection: "One who touches will become Tamei" -
something that contains Tum'ah (e.g. a bone with
marrow) is Tamei only if the Tum'ah can be touched.
3. Question (R. Zeira): If so, one who touches the skin
of a complete Neveilah should be Tahor!
4. Answer (Abaye): There are holes in the skin
(openings of the mouth, nose and eyes).
5. Question (Rav Papa): One who touches the Chelev (it
itself is Tahor) surrounding a kidney should be
6. Answer (Rava): Strands of meat exude from it.
1. Is it Tahor until punctured;
(f) Answer (R. Oshiya): It is Tamei.
2. Or, is it as if it was punctured?
(a) (Mishnah): A Sheretz egg in which a Sheretz formed is
Tahor; if there is a hole of any size in the egg, it is
(b) (Here, "Achbar"refers to a species that spontaneously
generates from dirt.)
(c) If an Achbar is half [developed into] flesh, and half
[still] dirt, one who touches the flesh is Tamei, one who
touches the dirt is Tahor.
1. R. Yehudah says, even one who touches the dirt
opposite the flesh is Tamei.
(d) (Gemara - Beraisa): "ha'Teme'im" includes the egg and
femur of a Sheretz (they are Teme'im);
1. Suggestion: Perhaps the egg is Tamei even if [the
inside] is unformed!
(e) Question: How big must the hole be?
2. Rejection: "ha'Sharetz" - just like the Sheretz is
formed, also the egg.
3. Suggestion: Perhaps the egg is Tamei even if there
is no hole!
4. Rejection: "One who touches will be Tamei" - it is
Tamei only if the Tum'ah can be touched.
(f) Answer: It must be as thick as a hair, in order that a
hair can enter and touch the inside of the egg.
(g) Version #1 (Mishnah): If an Achbar is half flesh... (one
who touches the flesh becomes Tamei).
(h) (R. Yehoshua ben Levi): This is only if it has the full
form of a Sheretz [on one side] from head to tail.
(i) Version #2 (Mishnah - R. Yehudah): Even one who touches
the dirt opposite the flesh is Tamei.
(j) (R. Yehoshua ben Levi): This is only if it has the full
form of a Sheretz [on one side] from head to tail.
1. Version #1 surely agrees to [the law of] Version #2
(without the full form of a Sheretz, R. Yehudah
would never Metamei the dirt)!
2. Version #2 argues with Version #1 (Chachamim Metamei
the flesh, even without the full form of a Sheretz).
