Avodah Zarah 49
1) "ZEH V'ZEH GOREM"
(a) Question: Does R. Yosi really say that Zeh v'Zeh Gorem is
forbidden?!
1. (Mishnah - R. Yosi): We may plant a shoot of Orlah
(only fruit is forbidden, not wood), but not a nut
of Orlah, because it is a fruit.
2. (Rav Yehudah): R. Yosi admits that if a nut (Rashi -
or shoots) of Orlah was planted, or the (Tosfos -
and the resulting) shoots were reinserted into the
ground or grafted, what grows is permitted (one of
the causes, the ground or the tree it was grafted
onto, is permitted).
3. A Beraisa supports Rav Yehudah.
4. Suggestion: Perhaps R. Yosi only forbids Zeh v'Zeh
Gorem regarding idolatry.
5. Rejection (Beraisa #1): If a field was fertilized
with manure of idolatry, or a cow was fattened with
fodder of idolatry, one may sow the field and eat
the cow.
6. (Beraisa #2): One must leave the field fallow (until
the improvement of the fertilizer wears off), he may
not eat the cow until it becomes thin again.
7. Suggestion: Beraisa #1 is like R. Yosi (Zeh v'Zeh
Gorem is permitted even regarding idolatry), Beraisa
#2 is like Chachamim.
(b) Answer: No, one Beraisa is like R. Eliezer, one is like
Chachamim.
(c) Question: Where do we find that R. Eliezer and Chachamim
argue about Zeh v'Zeh Gorem?
(d) Answer #1 (Mishnah - R. Eliezer): Se'or (sourdough, a
fermenting agent) of Chulin and of Terumah fell into a
dough; there was not enough of either one to make the
dough become Chametz, together they made it Chametz - the
dough has the law of the last one that fell in (if it was
Terumah, it may only be eaten by Kohanim in Taharah);
1. Chachamim say, no matter which fell in last, it is
forbidden (to a non-Kohen) only if there was enough
(Se'or of) Terumah to make it Chametz without the
Chulin.
2. (Abaye): R. Eliezer only permits (when the Chulin
fell in last) if the Terumah was removed before the
Chulin fell in; if not, it is forbidden. (He forbids
Zeh v'Zeh Gorem, Chachamim permit.)
(e) Rejection: Perhaps R. Eliezer also forbids Zeh v'Zeh
Gorem (e.g. they fell in at the same time;), he only
permits here because we attribute the entire action to
the final cause, whether or not the first cause was
removed (unlike Abaye)!
(f) Answer #2 (Mishnah): If wood from an Asheirah was used to
heat an oven for the first time, it must be destroyed
(because this solidifies the oven); if the wood was used
to heat an old oven, it must cool down (one may not bake
with that heat);
1. If one baked in the forbidden oven or with the
forbidden heat, the bread is forbidden; if the bread
became mixed with other bread, it is forbidden to
benefit from any of them;
2. R. Eliezer says, he takes the amount he benefited
(Rashi - the cost of wood equal to of the Asheirah
wood he used; Tosfos - the value of the loaf baked
with that wood) and throws it in the sea, then he
may benefit (Ba'al ha'Ma'or - but not eat; Ri - or
even eat) from all of them.
3. Chachamim: One cannot redeem idolatry!
(g) Question: Who are the Chachamim that argue with R.
Eliezer (about Zeh v'Zeh Gorem)?
1. Suggestion: They are the Chachamim of this Mishnah
(of the wood).
2. Rejection: They are more stringent than him (since
he forbids Zeh v'Zeh Gorem, all the more so they
do)!
(h) Answer: They are the Chachamim of the Mishnah of Se'or.
(i) Objection: Granted, those Chachamim permit Zeh v'Zeh
Gorem regarding Se'or, but perhaps they forbid regarding
idolatry!
(j) Conclusion: Indeed (as we said above (a:7), Beraisa #1 is
like R. Yosi, he permits Zeh v'Zeh Gorem even regarding
idolatry;
1. R. Yosi addresses Chachamim according to their
reasoning - I myself permit Zeh v'Zeh Gorem; you
forbid it, you should forbid vegetables even in
winter.
2. Chachamim permit, as Rav Mari brei d'Rav Kahana
taught (the gain on account of the leaves is offset
by the loss due to the shade).
(k) (Rav Yehudah): The Halachah follows R. Yosi.
(l) Question (Rav Amram): A certain garden is fertilized by
(blood of sacrifices to) idolatry - what is the law?
(m) Answer (Rav Yosef): Rav Yehudah taught, the Halachah
follows R. Yosi (the produce is permitted).

2) DERIVING BENEFIT FROM IDOLS
(a) (Mishnah): If wood from an Asheirah was used to heat an
oven for the first time, it must be destroyed; if the
wood was used to heat an old oven, it must cool down;
1. If one baked in the forbidden oven or with the
forbidden heat, the bread is forbidden; if the bread
because mixed with other bread, it is forbidden to
benefit from any of them;
2. R. Eliezer says, he takes the amount he benefited
(Rashi - the cost of wood equal to of the Asheirah
wood he used; Tosfos - the value of the loaf baked
with that wood) and throws it in the sea, then he
may benefit from all of them.
3. Chachamim: One cannot redeem idolatry!
(b) If wood from an Asheirah was used to make a Karkar (a
weaving tool), it is forbidden to benefit from it; if it
was used to weave a garment, the garment is forbidden; if
the garment became mixed with other garments, (and these
garments became mixed with other garments - R. Tam
deletes this from the text), it is forbidden to benefit
from any of them;
1. R. Eliezer says, he takes the amount he benefited
and throws it in the sea, then he may benefit from
all of them.
2. Chachamim: One cannot redeem idolatry!
(c) (Gemara): We must teach both cases.
1. If we only taught the first clause, one might have
thought that only there R. Eliezer permits (by
throwing the benefit into the sea), because the
prohibition (the wood) has been consumed before the
bread is finished, but regarding the Karkar, the
prohibition remains intact, one cannot throw away
money to permit the garment;
2. If we only taught the second clause, one might have
thought that only there Chachamim argue, because the
prohibition remains intact, but regarding the bread,
they agree to R. Eliezer.
3. Therefore, we must teach that they argue in both
cases.
(d) (Ze'iri): The Halachah follows R. Eliezer.
(e) (Rav Ada bar Ahavah): This only applies to bread, but if
a barrel of Yayin Nesech (wine offered to idolatry) was
mixed with permitted wine, it cannot be permitted (by
throwing its value in the sea);
(f) (Rav Chisda): This permits even wine.
(g) A barrel of Yayin Nesech was mixed with Reuven's wine.
(h) (Rav Chisda): Take four Zuz and throw them in the river,
this permits you to benefit from (but not drink) the
wine.
3) NULLIFICATION OF AN "ASHEIRAH"
(a) (Mishnah): If a Nochri took from it (for his needs)
chips, sticks or branches, even a leaf, it is nullified;
(b) If he shaved off pieces for its sake (to beautify it), it
is forbidden; if he did so for his own needs, it is
permitted.
(c) Question: What is the law of the shavings?
(d) Answer #1 (Rav Huna or Chiya bar Rav): They are
forbidden.
(e) Answer #2 (The other of Rav Huna and Chiya bar Rav): They
are permitted.
(f) Support (for the latter opinion - Beraisa): If a Nochri
shaved off pieces of idolatry for his own needs, it and
the shavings are permitted; if he did so for its sake, it
is forbidden; the shavings are permitted;
1. If a Yisrael shaved off pieces, whether for his own
needs or for its sake, it and the shavings are
forbidden (because a Yisrael cannot nullify
idolatry).
(g) (Rav): If an idolatry broke (by itself), every piece must
be nullified;
(h) (Shmuel): Idolatry is only nullified (if it broke) the
way it grows (e.g. leaves fell off).
(i) Objection: Just the contrary, it is not nullified the way
it grows!
(j) Correction: Rather, idolatry (that broke) only *needs to
be* nullified (if it broke) the way it grows.
(k) Suggestion: Rav holds that idolaters worship fragments of
idolatry, Shmuel holds that fragments are not worshipped.
(l) Rejection: No, all agree that fragments are worshipped;
1. They argue about fragments of fragments - Rav
forbids them, Shmuel permits them.
2. Alternatively, all agree that fragments of fragments
are permitted; they argue about an idolatry
consisting of rings that can be easily assembled:
i. Rav says, it does not become nullified when it
breaks, because anyone can easily assemble it;
3. Shmuel says, Idolatry only needs to be nullified the
way it grows - this is the way it grows, so it need
not be nullified.
***** PEREK R. YISHMAEL ****
4) MARKULIS
(a) (Mishnah): R. Yishmael says, if three rocks are found
next to each other near Markulis, they are forbidden; if
two are found, they are permitted;
(b) Chachamim say, rocks that are seen with it (Tosfos -
literally; Rashi - i.e. are very close) are forbidden,
those that are not are permitted.
(c) (Gemara): We understand Chachamim - they hold that
fragments are worshipped;
1. Rocks that are seen with it are forbidden, perhaps
they fell from it; rocks that are not seen with it
are permitted.
(d) Question: How does R. Yishmael hold?
1. If he holds that fragments are worshipped, even two
rocks should be forbidden;
2. If he holds that fragments are not worshipped, even
three rocks should be permitted!
(e) Answer (Rav Yitzchak bar Yosef): If we know that the
rocks fell from Markulis, all agree that they are
forbidden;
1. Even according to the opinion that fragments are not
worshipped, that applies to idolatry which does not
normally become fragmented;
i. Here, the idolatry is not riveted, it normally
comes apart.
(f) They argue when we do not know from where the rocks fell.
1. If they are very close to Markulis, all agree that
they are forbidden, perhaps they fell from it;
2. They argue when they are not close (but are within
four Amos).
