Previous daf Chulin 123
CHULIN 123-125 - Ari Kornfeld has generously sponsored the Dafyomi
publications for these Dafim for the benefit of Klal Yisrael.
1) THE "SHI'UR" OF FOUR "MIL"
(a) (R. Avahu citing Reish Lakish): Four Mil is the Shi'ur
for the following:
2) A "YAD" FOR SKIN BEING FLAYED
1. Kneading (Rashi - One who was hired to knead a dough
b'Taharah must walk four Mil to immerse vessels
(without extra compensation); Tosfos - one who wants
to hire someone to knead his dough should walk four
Mil to get someone who will do this b'Taharah);
(b) (Rav Nachman bar Yitzchak): Eibo said this, not R. Avahu;
he included a fourth case, trampling skins (in our
2. Prayer (one must walk four Mil in order to pray with
a Tzibur - Rashi;Tosfos - in order to immerse from
Tum'as Keri before praying);
3. Washing the hands (one must walk four Mil in order
to get water to wash before eating).
(c) (R. Yosi bar Chanina): Four Mil is the Shi'ur in the
direction one was going, but one need not backtrack even
(d) Inference (Rav Acha bar Yakov): If he can obtain them by
backtracking less than one Mil, he must do so.
(e) (Beraisa): If a troop of soldiers on the way to war
entered a house, the contents are Tamei, because a troop
always carries skins of heads (for witchcraft).
(f) This is not surprising - kings put on their head the skin
of R. Yishmael's head.
(a) (Mishnah): If one flays any animal to make a mat:
3) BREAKING A VESSEL TO MAKE IT "TAHOR"
1. If he only flayed the amount needed to grip the
skin, this can transmit Tum'ah (like a Yad; one
opinion in Tosfos says, like a Shomer).
(b) R. Yochanan ben Nuri says, the skin on the neck is not
connected regarding Tum'ah;
2. If he flays to make a water pouch, it is Tamei (like
a Yad or Shomer) until the chest;
3. If he flays from the legs, the entire skin is Tamei;
(c) Chachamim say, all the skin is Tamei until he finishes
(d) (Gemara) Question: What is the law after flaying enough
to hold the skin?
(e) Answer #1 (Rav): All the flayed skin is Tahor.
(f) Answer #2 (Rav Asi): The last Tefach flayed (the Tefach
adjacent to where the skin is still attached) is Tamei.
(g) Question (Beraisa): If one flays more than enough to hold
the skin, one who touches the flayed skin is Tahor.
1. Suggestion: This includes the last Tefach flayed.
(h) Answer: No, it excludes the last Tefach flayed.
(i) Question (Beraisa): The skin opposite (still on) the
flesh is Tamei.
1. Inference: The last Tefach flayed is Tahor.
(j) Answer: No - "skin opposite the flesh" includes the last
(k) Question (Beraisa): If one who flays any animal to make a
mat - the amount needed to hold the skin, this is Tamei;
1. The last Tefach flayed is Tahor.
(l) Answer: The case is, only two Tefachim have been flayed;
Rav Asi's law applies only when more has been flayed
(then the last Tefach is useful).
(m) (Beraisa #1): One Tefach is needed to hold the skin.
(n) Contradiction (Beraisa #2): Two Tefachim are needed to
hold the skin.
(o) Resolution (Abaye): Beraisa #1 discusses a double Tefach
(it equals two regular Tefachim)..
1. Support (Beraisa): A double Tefach is needed to hold
(a) (Mishnah): If a man was ripping a Tamei cloak to be
Metaher it, once he rips the majority, it becomes Tahor
(Tosfos - retroactively from when he started tearing).
(b) (Rav Nachman): This is only if it is a Tevul Yom (it was
immersed today, even if not torn it would be fully Tahor
1. Since he was willing to immerse it (even though this
is bad for it), we are not concerned that he will
not tear the majority.
(c) Objection #1 (Rabah): We must decree that tearing the
majority does not Metaher on the day it became Tamei,
lest people will think that vessels become fully Tahor
through immersion on the same day!
2. If he did not immerse it, we decree that he must
tear it fully to be Metaher it, lest he will not
tear the majority.
(d) Objection #2 (Rabah): R. Eliezer b'Rebbi Shimon forbids
severing the Simanim of Olas ha'Of during Melikah, we cut
only the majority;
4) TEARING SKIN
1. He does not decree (Tosfos - that he must cut a
large majority) lest he will not cut the majority!
(e) Answer (to Objection #1 - Rav Yosef): People will see
that the majority was torn and understand that this was
Metaher it, not the immersion.
(f) Answer (to Objection #2 - Rav Yosef): Kohanim (who do
Melikah) are zealous, we need not decree lest they will
not cut enough.
(g) Question (against Rav Nachman - Mishnah): If one flays
any animal, Tamei or Tahor, to make a mat:
1. If he flayed only the amount needed to hold the
skin, it is Tamei;
(h) Answer: Regarding Tum'ah mid'Oraisa, we would make such a
2. If he flayed more, it is Tahor - we do not decree
lest he will flay only the amount needed (and
mistakenly think that it is Tahor)!
1. The Mishnah discusses only Tum'ah mid'Rabanan.
(i) Question: This applies when the animal is Tahor and the
man is Tamei mid'Rabanan;
1. But the Mishnah also discusses when the animal is
Tamei (a Neveilah) - this is mid'Oraisa!
(j) Answer: The Mishnah does not discuss Tamei species,
rather, a Tereifah of a Kosher species, which is Tamei
(k) Question: A Tereifah is not Tamei!
(l) Answer: It can be, like Shmuel's father taught.
1. (Shmuel's father): If a Tereifah Kodesh animal was
slaughtered, it is Tamei mid'Rabanan.
(m) Question (against Rav Nachman - Beraisa - R. Dostai ben
Yehudah): If one flays a Sheretz, the flayed skin is
connected (and is Metamei like the Sheretz) until he
flays it all.
1. Inference: (This is because it is hard to flay
Sheratzim - but) if one flays a camel, only Kedei
Achizah (the amount needed to hold onto) is
connected (even though the Tum'ah is mid'Oraisa)!
(n) Answer: No - rather, regarding a camel, the skin on the
neck is not connected;
2. (We do not decree to be Metamei outside of Kedei
Achizah on account of within Kedei Achizah!)
1. The Beraisa is like R. Yochanan ben Nuri (in our
(a) Version #1 (Rav Huna): If one tears the majority of a
1. The resulting pieces are Tehorim only if neither is
large enough to make a turban;
(b) (Reish Lakish): Tearing the majority is Metaher only
regarding a cloak;
2. If a piece is big enough, it is Tamei.
1. Skin is strong (it can be sewn together like
before), it remains Tamei.
(c) (R. Yochanan): Also regarding skin, tearing the majority
is Metaher, it is not strong.
(d) Question (R. Yochanan - Mishnah - R. Yehudah): If skin is
Tamei Midras (it is made to be sat on, and a Nidah (or
Zav...) sat on it, making it an Av ha'Tumah):
1. If the owner planned to cut it into straps or shoes,
once he starts cutting it, it is Tahor;
(e) Answer: Reish Lakish considers it connected only when it
is cut down the middle, not when strips are cut from the
2. Chachamim are Metamei until he cuts it into pieces
less than five Tefachim [by five Tefachim].
3. Summation of question: Less than five Tefachim is
Tahor - we do not say, since it is strong, we
consider it to be connected!
(f) Question (R. Yirmeyah - Mishnah): If one flays any
animal, Tamei or Tahor, to make a mat:
1. If he flayed only the amount needed to hold the
skin, it is Tamei.
(g) Answer (R. Avin): Each piece flayed is considered
disconnected, for it will not be joined to the meat
2. If he flayed more, it is Tahor - we do not consider
it to be connected because the skin is strong!
(h) Question (against Reish Lakish - Rav Yosef - Mishnah): R.
Yochanan ben Nuri says, the skin on the neck is not
connected regarding Tum'ah.
1. According to Reish Lakish, we should consider it to
still be connected!
(i) Answer (to both questions - Abaye): The Tana'im argue
about a Shomer that will become detached by itself.
2. Counter-question (Abaye - Seifa - Chachamim): It is
i. This supports Reish Lakish and opposes R.
1. Chachamim consider it a Shomer, R. Yochanan ben Nuri
