Previous daf Chulin 125
CHULIN 123-125 - Ari Kornfeld has generously sponsored the Dafyomi
publications for these Dafim for the benefit of Klal Yisrael.
1) MEAT INSIDE BONES
(a) (Mishnah): One who touches a femur of a Mes or Kodshim,
whether or not there is a hole in it, becomes Tamei;
2) IS TOWERING LIKE TOUCHING?
1. One who touches a femur of a Neveilah or Sheretz
becomes Tamei only if there is a hole of in it, even
(b) (Gemara) Inference: A femur of a Mes has only Tum'as
Maga, not Tum'as Ohel.
2. Question: What is the source that it is even Metamei
3. Answer: "One who touches...and one who carries" -
those things that are Metamei b'Maga are Metamei
(c) Question: What is the case?
1. If there is a k'Zayis of flesh on the bone - it
should also be Metamei b'Ohel!
(d) Answer: There is not a k'Zayis of flesh on the bone.
(e) Question: If there is a k'Zayis of marrow inside, the
Tum'ah should exude and be Metamei b'Ohel!
(f) Answer: There is not a k'Zayis of marrow inside.
(g) Question: If we say that marrow inside nourishes meat
outside - even if there is less than a k'Zayis of marrow
inside (Tosfos; Rashi - there is no marrow inside, since
marrow could grow again, and then it could help meat grow
outside), we should consider the bone like a proper limb
(which is Metamei b'Ohel)!
(h) Answer (Rav Yehudah brei d'R. Chiya): Our Mishnah teaches
that marrow inside does not nourish meat outside.
(i) Question: If there is not a k'Zayis of meat (or marrow),
why is it Tamei regarding Kodshim?
(j) Answer #1: The first clause (Tum'as Mes) is when there is
not a k'Zayis of marrow, the second clause (Kodshim) is
when there is a k'Zayis; each teaches a Chidush:
1. The first clause teaches that marrow inside does not
nourish meat outside;
(k) Answer #1A (Abaye): [The cases in the Mishnah are like
above, but] marrow inside *does* nourish meat outside;
2. The second clause teaches that bones that held Nosar
are Tamei (mid'Rabanan).
i. (Rav Mari): Bones of Kodshim that once held
Nosar are Tamei, because they once held
3. Regarding Neveilah, even if there is a k'Zayis of
marrow, a bone is Tamei only if it has a hole.
1. The case is, the bone was cut.
(l) Answer #2 (R. Yochanan): The entire Mishnah is when there
is a k'Zayis of marrow inside; marrow inside *does*
nourish meat outside;
2. (R. Elazar): If a femur was cut lengthwise, it is
Tamei (for the marrow still nourishes meat outside);
if it was cut widthwise, it is Tahor.
i. A way to remember this is a date tree (if one
cuts it lengthwise (from the ground up), it
will live; if cut widthwise, it will die).
1. Regarding Tum'as Mes, when the Mishnah says it has
Tum'as Maga, it means Tum'as Ohel.
(m) Question: If marrow nourishes meat outside, regarding
Neveilah and Sheratzim, the bone should be Tamei like a
limb, even if there is no hole!
(n) Answer (R. Binyamin bar Gidal): The case is, the marrow
is dry (it cannot nourish meat outside).
1. Regarding Tum'as Mes, the Tum'ah pierces (goes
straight through) the bone;
2. Regarding Neveilah, since dry marrow cannot nourish
meat outside, it is not Tamei like a limb;
i. It is only Tamei if there is a hole.
(a) Support (R. Avin - Mishnah): If one touches a
half-k'Zayis (of Tum'as Mes) and towers over (or is
towered over by) a half-k'Zayis, he is Tamei.
1. We understand this if towering has the same law like
2. Question: If towering is not like touching, why do
the half-k'Zeisim join?
i. (Mishnah): Tum'os of the same name (type) join
up, Tum'os of different names do not join.
3. Counter-question: If towering is like touching, the
half-k'Zeisim should join also in the Mishnah (but
they do not)!
3) COVERED "TUM'AH"
(b) Question: Which Tana considers towering like touching?
i. (Seifa): One who touches a half-k'Zayis [of
Tum'as Mes] and is under a common roof with a
half-k'Zayis, he is Tahor.
4. Answer (R. Zeira): The Mishnah discusses Tum'ah
between two chests (there is not a Tefach in
between) - in such a case, Tum'as Ohel is like
touching. (This refutes the support for R. Yochanan,
who said that normal towering is like touching.)
(c) Answer: It is R. Yosi.
1. (Beraisa - R. Yosi): A spoon full of Rekev (dust of
a decayed Mes) has Tum'as Maga, Masa and Ohel.
i. We understand Masa and Ohel - the entire amount
is moved or towered over.
2. Question: How can it be Metamei through Maga - one
cannot touch the full amount (it is not connected)!
3. Answer: We must say, Maga refers to Ohel, the Tana
calls it Maga.
4. Question: But it lists Maga, *and* Ohel!
5. Answer #1 (Abaye): Towering less than a Tefach above
the Tum'ah is like Maga; towering more than a Tefach
above the Tum'ah is not like Maga.
6. Answer #2 (Rava): Towering more than a Tefach above
the Tum'ah is also like Maga.
7. Question: What type of Ohel is not like Maga?
8. Answer: Being under a common roof with Tum'ah is
(a) Rava: I learn from a Mishnah.
1. (Mishnah - R. Yosi): If bed ropes or poles (that are
interwoven) separate between a house and the second
story, they block Tum'as Mes from passing from one
to the other.
(b) Rejection (Abaye): Really, the ropes are less than a
Tefach over the Mes;
2. If the ropes (or poles) were stretched in the air
over a Mes - one who touches (puts his hand) over a
rope is Tahor, one who touches (over the Mes) in the
airspace between the ropes is Tamei.
3. Question: What is the case?
i. If the ropes are less than a Tefach over the
Mes - even over the ropes should be Tamei, just
like Tum'ah pierces through the clothing on a
4. Answer: Rather, the ropes are more than a Tefach
over the Mes, and the Tana calls this Maga.
1. This is unlike clothing on a Mes - clothing on a Mes
is Batel to the Mes, the ropes are not!
(c) Question: Still, it should be like covered Tum'ah [of
Mes, with less than a Tefach between the Tum'ah and the
covering], which pierces through the covering!
(d) Answer: R. Yosi holds that covered Tum'ah does not pierce
(e) Question: What is the source to say this?
(f) Answer (Mishnah): If a cupboard is a Tefach deep, but the
opening is less than a Tefach:
1. If Tum'ah is in the cupboard, [everything in] the
house is Tamei; if Tum'ah is in the house,
(everything in) the cupboard is Tahor;
(g) R. Yosi says, the house is Tahor, because the Tum'ah
might leave less than a k'Zayis at a time, or it might be
burned before it leaves.
2. The reason is, it is normal for Tum'ah to leave, it
is not normal for Tum'ah to enter.
