BAVA BASRA 87 & 88 - dedicated by an admirer of the work of the Dafyomi
Advancement Forum, l'Iluy Nishmas Mrs. Gisela (Golda bas Reb Chaim Yitzchak
Ozer) and Reb Yisroel Shimon (ben Reb Shlomo) Turkel, A"H.
1) MEASURING OUT PART OF THE SALE (cont.)
(a) Question (against Rav and Shmuel - Beraisa): It is
forbidden to hire a worker, paying him now 30 Dinarim for
30 days of work to be done later, when the normal wages
are more (a Sela per day, on account of Ribis);
2) SELLING LIQUIDS
1. If he hires him to begin now, and pays immediately
100 Dinarim for 100 days of work, it is permitted,
even though the normal wages will later be more;
(b) (Mishnah): If it was attached to the ground and he
detached any amount, he acquires.
2. If 'A Kor for 30, each Se'ah for a Sela', after each
Se'ah is measured out, neither can retract, here
also, the wages of each day are finished after that
day, he works the last 30 days for 30 Dinarim he
received in advance, it should be forbidden (as in
the first clause)!
3. Counter-question (Rava): Also in the first clause,
it should be permitted to hire oneself for less than
the normal wages!
4. Question: Why is it forbidden in the first clause,
but not in the second?
5. In the first clause, he is paid before he starts
working, it looks like Ribis;
i. In the second clause, he starts working
immediately, it does not looks like Ribis.
(c) Question: Why does he acquire everything by detaching any
(d) Answer (Rav Sheshes): The case is, the seller said 'Go
make any improvement in the field and acquire it all'.
(a) (Mishnah): If Reuven sells wine or oil to Shimon, and the
price went up or down: before the measure is filled, the
wine still belongs to Reuven; after the measure is
filled, the wine belongs to Shimon.
1. If a middleman was selling, if the barrel broke, he
suffers the loss.
(b) He must hold the bottle (after the wine or oil stops
flowing) until three drops come out;
1. After this, if he tilted the bottle and some drops
accumulated, they belong to Reuven.
(c) A grocer need not wait for three drops;
(d) R. Yehudah says, just before Shabbos he need not wait.
(e) (Gemara) Question: Who owns the measuring vessel?
1. If Shimon - before the measure is filled, the wine
should belong to Shimon!
(f) Answer: Reuven owns it.
(g) Question: After the measure is filled, the wine should
still be Reuven's!
(h) Answer (R. Ila'i): It belongs to a middleman.
(i) Question: The next clause says, if a middleman was
selling, if the barrel broke, he suffers the loss -
implying that the first clause does not discuss a
(j) Answer: The first clause discusses the vessel of a
middleman, the next clause is when the middleman himself
(k) (Mishnah): After this, if he tilted the bottle and some
drops accumulated, they belong to Reuven.
(l) Contradiction (R. Elazar - Mishnah): (If one declared a
bottle of wine to be Terumah), if he tilted the bottle
(after pouring it out) and some drops accumulated, they
(m) Answer (R. Avahu): Here, they belong to Reuven because
Shimon despairs (of getting any more) after the three
3) ENTRUSTING OBJECTS OF VALUE TO A MINOR
(n) (Mishnah): A grocer need not wait for three drops (R.
Yehudah says, just before Shabbos he need not wait).
(o) Question: Does R. Yehudah argue on the clause before this
(that always obligates a regular person), and he is
lenient just before Shabbos?
1. Or, does R. Yehudah argue on this clause (that
always exempts a grocer), and he is stringent
(except for just before Shabbos)?
(p) Answer (Beraisa - R. Yehudah): Just before Shabbos, a
grocer need not wait because he is very busy.
(a) (Mishnah): Reuven sent his son (a minor, with a coin
worth two Isarim) to a grocer (Shimon), who gave him an
Isar worth of oil, and an Isar change. The child broke
the flask and lost the Isar - Shimon is liable;
(b) R. Yehudah exempts him, for he did as Reuven wanted.
(c) Chachamim admit, if the child held the flask and Shimon
measured into it, he is exempt.
(d) (Gemara) Question: We understand the argument about the
Isar and the oil: Chachamim say that the child was sent
to inform Shimon to send (the oil and Isar) with an
adult, R. Yehudah says that he wanted Shimon to send them
with the child;
1. Why do Chachamim obligate him for the flask - Reuven
knowingly gave it to his son (who is prone to break
(e) Answer #1 (R. Hoshaya): The case is, Reuven sells flasks;
Shimon picked it up to see if he wants to buy it.
1. (Shmuel): If one takes a vessel from a craftsman to
see if he wants to buy it, and Ones occurred, he is
(f) Objection: If so, Shmuel's law is like Chachamim, but not
like R. Yehudah!
(g) Answer #2 (Rabah and Rav Yosef): The case is, Shimon
sells flasks (it was his flask); they argue about the
flask as they argue about the Isar and oil.
(h) Objection (end of the Mishnah): Chachamim admit, if the
child held the flask and Shimon measured into it, he is
1. If Shimon was supposed to send the oil with an
adult, why is he exempt? (Tosfos - Rabah and Rav
Yosef explain, the end of the Mishnah is when Reuven
sent his son with a flask, but the Gemara does not
