Avodah Zarah 37
1) THE CONDITIONAL GET
(a) R. Yehudah Nesi'ah: Last night, we permitted oil of
Nochrim.
(b) R. Simla'i: You will even permit their bread!
(c) R. Yehudah Nesi'ah: No, for then we would be called a
permissive Beis Din.
1. (Mishnah): Yosi ben R. Yo'ezer testified that Ayil
Kamtza (a species of grasshopper) is permitted, that
liquids (blood and water) in the Azarah (courtyard
of the Mikdash) are Tahor, and that one who touches
a corpse is Tamei (this will be explained (very
differently) later), and they called him 'permissive
Yosi'.
(d) R. Simla'i: He permitted three things, bread would only
be your second!
(e) R. Yehudah Nesi'ah: I also permitted a conditional Get.
1. (Mishnah): Reuven gave a Get to his wife, saying
'This is your Get if I do not return within 12
months', and he died during the 12 months - (since
he died before the Get takes effect,) the Get does
not take effect;
2. (Beraisa): Raboseinu permitted her to marry (even if
she would have fallen to Yibum without the Get).
i. (Rav Yehudah): 'Raboseinu' is the Beis Din that
permitted oil; they hold like R. Yosi, who says
that the date on a document (on condition)
proves that it was intended to take effect from
that day (therefore, the Get took effect before
he died).
ii. (R. Aba brei d'R. Chiya bar Aba): R. Yehudah
Nesi'ah's colleagues did not agree with him.
(f) Question (R. Elazar, of a Chacham): Did you permit her to
marry immediately after her husband died (since the
condition will surely be fulfilled);
1. Or, must she wait until 12 months (Ramban - then,
the condition is properly fulfilled; Tosfos - this
is a decree, lest other women remarry within the
year even though their husbands did not die)?
2. The Chacham: Why didn't you ask me regarding the
Mishnah?
i. (Mishnah): 'This is your Get *from now* if I do
not return within 12 months', and he died
during the 12 months - the Get takes effect.
ii. You could ask, may she remarry immediately
(since he will not come), or must she wait 12
months?
3. R. Elazar: I asked about the Beraisa, because you
were part of the Beis Din that permitted that case.
(g) (Abaye): All agree that if he said '(This is your Get)
*when* the sun comes out', it does not take effect until
morning, if he died before morning, the Get is void
(since it did not take effect in his lifetime);
1. All agree that if he said '*On condition that* the
sun will come out', it takes effect from now (but
she may not marry until morning), if he died before
morning, the Get is valid;
i. (Rav Huna): 'On condition that' is like saying
'from now'.
2. They argue when he said '*Im* (if) the sun will come
out': R. Yehudah Nesi'ah holds like R. Yosi, the
date on the Get proves that he wants it to take
effect from now, this is like saying 'From today if
I die' (a valid Get);
i. Chachamim argue with R. Yosi's law (or say that
it does not apply here, for the stipulation is
not written in the Get - Tosfos), it is as if
he said 'This is your Get if I die' (which is
invalid).
2) THE LENIENCIES OF YOSI BEN YO'EZER
(a) (Mishnah): Yosi ben R. Yo'ezer testified that Ayil Kamtza
is permitted, that liquids in the Azarah are Tahor, and
that one who touches a corpse is Tamei (this will be
explained (very differently) later), and they called him
'permissive Yosi'.
(b) Question: What is Ayil Kamtza?
(c) Answer #1 (Rav Papa): Shushiva (a long-headed
grasshopper).
(d) Answer #2 (Rav Chiya bar Ami): Susbil (a species of
grasshopper).
1. Rav Papa says that (Yosi and Chachamim) argue about
long-headed grasshoppers: Yosi permits them,
Chachamim forbid them.
2. Rav Chiya bar Ami says that all agree that
long-headed grasshoppers are forbidden (Tosfos -
permitted);
37b---------------------------------------37b
i. They argue about species whose wings cover a
bare majority of the grasshopper: Yosi permits
them, Chachamim require that the wings cover a
clear majority of the grasshopper.
(e) (Mishnah): Liquids in the Azarah are Tahor.
(f) Question: What does this mean?
(g) Answer #1 (Rav): They do not receive Tum'ah at all.
(h) Answer #2 (Shmuel): They do not impart Tum'ah, but they
themselves receive Tum'ah.
(i) Rav says that they do not receive Tum'ah at all - he
holds that liquids do not receive Tum'ah mid'Oraisa, only
mid'Rabanan;
1. Chachamim decree Tum'ah on other liquids, but not in
the Azarah.
(j) Shmuel says that liquids in the Azarah do not impart
Tum'ah - he holds that liquids receive Tum'ah mid'Oraisa,
they only impart Tum'ah mid'Rabanan;
1. Chachamim decreed that other liquids impart Tum'ah,
not liquids in the Azarah.
(k) (Mishnah): And that one who touches a corpse is Tamei,
and they called him 'permissive Yosi'.
(l) Question #1: This last ruling is a stringency, not a
leniency!
(m) Question #2: This law is explicit in the Torah (why did
he have to testify about it) - "V'Chol Asher Yiga...O
v'Mes"!
(n) Answer #1 (to both questions): Mid'Oraisa, one who
touches a corpse is Tamei (for seven days); Chachamim
decreed that one who touches one who touched a corpse is
also Tamei (for seven days), Yosi annulled the decree,
and ruled according to Torah law (he can immerse and
become fully Tahor at nightfall).
1. Objection: Mid'Oraisa, one who touches one who is
touching a corpse is Tamei - "V'Chol Asher Yiga Bo
ha'Tamei Yitma" (implying, for seven days)!
2. Answer (Rabanan citing Rav Nachman): Mid'Oraisa, one
who touches one who is touching a corpse is Tamei
(seven days), one who touches one who *touched* a
corpse is Tamei until nightfall;
i. Chachamim decreed that also in this latter case
he is Tamei for seven days; Yosi annulled the
decree, and ruled according to Torah law.
3. Question: How do we know that mid'Oraisa he is Tamei
until nightfall?
4. Answer - Contradiction: It says "Ha'Noge'a
b'Mes...v'Tamei Shivas Yamim", and "V'Chol Asher
Yiga Bo ha'Tamei Yitma (implying, also seven days),
and "veha'Nefesh ha'Noga'as Titma Ad ha'Arev"!
i. Answer: The second verse discusses one who
touches one who is touching a corpse, the last
verse discusses one who touches one who touched
a corpse.
5. Objection (Rava): Rav Nachman did not explain
thusly!
(o) Answer #2 (Rava citing Rav Nachman): Yosi ruled that
doubtful Tum'ah in a public domain is Tahor.
(p) Question: But all agree to this, we learn from Sotah!
1. Doubtful Tum'ah of a Sotah is Tamei, but this only
applies to a private domain - in a public domain,
doubtful Tum'ah is Tahor!
(q) Answer: R. Yochanan taught, the Halachah is, it is Tahor,
but we do not publicize this;
1. Yosi taught that we publicize it.
(r) Support (Beraisa - R. Yehudah): Yosi put beams to show
people where is considered the public domain (regarding
Tum'ah);
1. R. Yanai would tell people (who became doubtfully
Tamei in a public domain) to immerse.
3) BISHUL AKUM
(a) (Mishnah): Bishul Akum (cooked foods of Nochrim) is
forbidden.
(b) Question: What is the source of this?
(c) Answer #1 (R. Chiya bar Aba): "Ochel ba'Kesef Tashbireni
v'Achalti u'Mayim..." - just as we may drink water of
Nochrim, it has not changed, also we may only eat their
food if it has not changed.
(d) Objection: If so, it should be forbidden to eat Kelayos
(wheat that was dried in an oven) of a Nochri!
1. Suggestion: Perhaps that is true!
2. Rejection (Beraisa): If a Nochri made Kelayos out of
wheat, it is permitted.
(e) Answer #2: Rather, just as we may drink their water, it
is in its natural form, also we may only eat their food
if it is in its natural form.
(f) Objection: If so, if a Nochri ground wheat, the flour
should be forbidden!
1. Suggestion: Perhaps that is true!
2. Rejection (Beraisa): If a Nochri made Kelayos out of
wheat, and flour or fine flour of a Nochri - these
are permitted.
(g) Answer #3: Just as we may drink water of Nochrim, it has
not changed through fire, also we may only eat their food
if it has not changed through fire.
(h) Objection: The Torah does not say that it depends if it
changed through fire!
(i) Answer #4: Chachamim decreed against Bishul Akum, the
verse is only an Asmachta.
