1) WHO CAN RETRACT FROM A SALE?
(a) (Gemara - Rav Chisda): If Levi sold to Yehudah something
worth five (e.g. Zuz) for six, and its value increased to
eight, Yehudah can retract, not Levi, since Yehudah was
overcharged;
1. Yehudah can say: had you not overcharged me, you
could not retract - now that you overcharged me, can
you retract?!
(b) Support (Mishnah): If Reuven sold good wheat, and it was
found to be bad, Shimon can retract.
(c) (Rav Chisda): If Levi sold something worth six for five,
and its value decreased to three, Levi can retract, not
Yehudah, since Levi was underpaid;
1. He can say: had you not underpaid me, you could not
retract - now that you underpaid me, can you
retract?!
(d) Support (Mishnah): If Reuven sold bad wheat, and it was
found to be good, Reuven can retract.
(e) Question: What does Rav Chisda teach that we do not know
from the Mishnah?
(f) Answer: One might have thought, either can retract in Rav
Chisda's case (when the price was too high or low);
1. The Mishnah is when the price is correct, but the
quality was not as stated;
2. Version #1 (Rashi): When he sold good and it was
found to be bad, Reuven cannot retract, because
Shimon can say, there was no mistake - "Ra Ra Yomar
ha'Koneh" (and likewise, the seller always claims
that the merchandise is good, even if he knows it is
not).
3. Version #2 (Ri): When he sold good and it was found
to be bad, the Mishnah teaches that Shimon can
retract;
i. One might have thought, Reuven can say, there
was no mistake - "Ra Ra..." (you know that the
seller always claims that the merchandise is
good, even when it is not).
2) THE COLOR OF THE SUN
(a) (Mishnah): He sold Shechamtis (red wheat), and it was
found to be white...
(b) Inference (Rav Papa): Since the Mishnah mentions white
wheat, this teaches that the sun is red (Shechamtis must
refer to red wheat, and it is called Shechamtis because
it looks like the Chamah (sun)).
(c) Support: The sun appears red in the morning and evening;
1. It does not appear so the rest of the day because
our eyes cannot see so clearly because it is so
bright.
(d) Question (Beraisa): "The appearance (of Tzara'as) Amok
Min ha'Or" - as the sun appears, deeper than the shade.
1. Tzara'as appears white!
(e) Answer: It is as the sun appears regarding deepness, but
not regarding color (really, the sun is red).
(f) Question: The one who asked the question understood that
the sun is white - how did he understand why it appears
red in the morning and evening?
(g) Answer: In the morning its rays pass through the roses of
Gan Eden; in the evening, its rays pass through the
entrance of Gehinom;
1. Some say, vice-versa.
3) WINE IN PLACE OF VINEGAR
(a) (Mishnah): If he sold wine, and it was found to be
vinegar, either can retract.
(b) Suggestion: Our Mishnah is like Rebbi, not like
Chachamim.
84b---------------------------------------84b
1. (Beraisa): Wine and vinegar are the same species;
2. Rebbi says, they are two species.
(c) Rejection: The Mishnah is even like Chachamim - Chachamim
only consider it one species regarding Ma'aser and
Terumah, as R. Ila'i;
1. (R. Ila'i): If one separates bad produce to be
Terumah on good produce, it takes effect - "V'Lo
Sis'u Alav Chet ba'Harimechem Es Chelbo";
i. If it did not take effect, he would not bear
sin!
2. But regarding a sale, all agree that some people
prefer wine, others prefer vinegar.
4) ACQUISITION THROUGH MESHICHAH AND MEASURING
(a) (Mishnah): If Reuven sold produce to Shimon (for a price
per unit measure) and he did Meshichah but did not
measure it, Shimon acquires;
1. If he measured but did not do Meshichah, he does not
acquire;
2. If Shimon is clever, he will rent the premises (to
acquire immediately).
(b) If Shimon buys flax from Reuven, he does not acquire
until he moves it from place to place;
1. If it was attached to the ground and he detached any
amount, he acquires.
(c) (Gemara - Rav Asi citing R. Yochanan): If he measured and
put it in a Simta (an adjunct to a public domain where
people are permitted to rest things), he acquires.
(d) Suggestion (R. Zeira): Perhaps you only heard that this
applies when he measured into his box in the Simta?
(e) Rejection (Rav Asi): That is obvious, R. Yochanan would
not need to teach that case!
(f) Question: Did R. Zeira accept this answer?
(g) Answer: We learn from the following:
1. (R. Yanai (R. Yochanan's Rebbi) citing Rebbi):
Partners in a joint Chatzer can acquire one from the
other.
2. Suggestion: They acquire by putting on the ground.
(h) Rejection: No, by putting in the other's vessel.
(i) Support (R. Yakov citing R. Yochanan): If he measured and
put it in a Simta, he did not acquire.
1. Question: But R. Yanai and R. Yochanan (according to
Rav Asi) said that he acquires!
2. Answer: We must say, if he puts it in the other's
vessel he acquires, if he puts it on the ground he
does not acquire (Rav Asi misunderstood R.
Yochanan's teaching).
(j) Question (against Rav Asi - Mishnah): If he measured but
did not do Meshichah, he does not acquire.
1. Suggestion: This is in a Simta.
(k) Answer: No, it is in a public domain.
(l) Question (beginning of the Mishnah): If he did Meshichah
but did not measure it, Shimon acquires;
1. Meshichah does not acquire in a public domain!
i. (Abaye and Rava): Mesirah acquires in a public
domain, or in a Chatzer that does not belong to
both of them;
ii. Meshichah acquires in a Simta or in their joint
Chatzer;
iii. Hagbahah acquires everywhere.
(m) Answer: The Mishnah means, he acquires by doing Meshichah
from the public domain to a Simta.
(n) Question (end of the Mishnah): If Shimon is clever, he
will rent the premises.
1. No one owns the public domain to rent it to Shimon!
(o) Answer: The Mishnah means, if he is in a private domain,
if Shimon is clever, he will rent the premises.
