BAVA METZIA 50 (27 Teves) - in honor of the memory of Hagaon ha'Gadol Rav
Pinchas Hirschprung, well-known and much loved Rav of Montreal, Talmid of
Hagaon Rav Meir Shapiro (founder of the Dafyomi cycle), on the day of his
Yahrzeit. Dedicated by his son, Rav Yitzchak Hirschprung, may he be blessed
with long years and all that he needs.
(a) We ask whether less than a sixth according to the Rabbanan of Rebbi
Tarfon is considered Mechilah immediately or only after he has had time to
show the article to a merchant ... .
What are the ramifications of this
(b) How do we try to prove that it must be considered Mechilah immediately
(and he can no longer retract)?
(c) How do we refute this proof? What *is* the difference between the two?
(a) We learned in our Mishnah that when the merchants of sLud heard that
Rebbi Tarfon gave the purchaser all day to retract, they relented and
reverted to the opinion of the Rabbanan.
Answers to questions
What do we mean when we suggest
that less than a third according to Rebbi Tarfon, is presumably equivalent
to less than a sixth according to the Rabbanan?
(b) How do we try to prove from here that the Mechilah must take place only
after the time it takes to show the article to a merchant ... ? What would
the merchants then stand to lose?
(c) What would be the problem if the Mechilah was immediate?
(d) We answer this Kashya by reestablishing the amount between a sixth and a
third according to Rebbi Tarfon like a sixth (rather than less than a sixth)
according to the Rabbanan.
In which point does he then argue with them?
(a) If as we just concluded, Rebbi Tarfon only argues with the Rabbanan in
that they consider between a sixth and a third Bitul Mekach and he considers
it Ona'ah, what problem will that pose on the merchants of Lud?
We refute the proof that the Rabbanan's Shiur of Bitul Mekach must be
forever (explaining the merchants happiness even if the Rabbanan gave Bitul
Mekach the same Shiur as Ona'ah) by establishing their Machlokes by exactly
(b) We are about to ask what the Shiur of Bitul Mekach is according to the
What are the two possibilities?
(c) How do we try to resolve the She'eilah and answer the Kashya
(d) In that case, why did the merchants of Lud revert to the Chachamim when
Rebbi Tarfon told them the purchaser had all day to retract (besides the
fact that his Shiur is not then really that different from the Rabbanan's to
make it an advantage [as we will explain shortly])?
What would then be their Machlokes?
(a) We ask what the Shiur of Bitul Mekach is according to the Rabbanan.
Assuming that the Shiur is the same as that of Ona'ah, what will be the
difference between Ona'ah and Bitul Mekach?
(b) How do we try to resolve the She'eilah from the fact that the merchants
of Lud reverted to the Chachamim when Rebbi Tarfon told them the purchaser
had all day to retract? What would be the problem with that according to the
other side of the She'eilah?
(c) Even assuming that the Rabanan's Shiur by Bitul Mekach is the same as
that of Ona'ah, why did the merchants choose to revert to the Rabbanan,
seeing as they still had the advantage of Sh'tus according to Rebbi Tarfon
(which is Mechilah, as we explained above)?
(d) How do we reject the above resolution?
(a) Rava issues a final ruling regarding all three Dinim.
What Shiur does
he give regarding ...
(b) How does Rava present the basic Halachah of Ona'ah?
- ... Pachos mi'Sh'tus?
- ... Sh'tus?
- ... Yeser al Sh'tus?
(c) On what basis does he cite the Halachah differently than the Beraisa
that we quoted above?
(d) If this is the opinion of Rebbi Nasan in the Beraisa that follows, who
is the Tana who argues with him (giving him the option of retracting
completely from the deal)?
(a) The Tana of our Mishnah permits the purchaser to retract up to the time
that he could show the object to a merchant ... .
Answers to questions
What does Rav Nachman
comment on this?
(b) On what grounds does he make such a distinction?
(c) How do we try to support Rav Nachman from the merchants of Lud who
reverted to the opinion of the Rabbanan when they heard Rebbi Tarfon give a
Shiur of the whole day?
(d) How do we reconcile the merchants of Lud even with the contention that
the seller is subject to the same time-limit as the purchaser?
