Previous daf Bava Basra 171
BAVA BASRA 171 (Rosh Hashanah) - dedicated in honor of the birth of a baby
boy to Harav Elimelech Kornfeld (of the Gra Shul, Ramat Beit Shemesh). Mazel
Tov - may he and his wife raise the new addition l'Torah l'Chupah ul'Ma'asim
(a) The full Beraisa (cited earlier by Rav Nachman) citing Rebbi Yehudah,
speaks about Reuven who pays Shimon five hundred Zuz out of his thousand Zuz
debt. Rebbi Yehudah rules there - that the witnesses tear up the Sh'tar and
write a new one backdated from the time of the original.
(b) Rebbi Yossi's two reasons for writing a receipt are - a. to force Reuven
to pay the remainder of his debt quickly, and b. to enable Shimon to claim
from the date on the original Sh'tar.
(c) Rebbi Yossi found it necessary to add the second reason, in spite of the
fact that Rebbi Yehudah says exactly the same - because (apparantly he made
the first statement, with reference to Rebbi Yehudah's statement in our
Mishnah, where he is vague in this point).
(d) So when he gave the two reasons, what he really meant to say was - that
if Rebbi Yehudah permitted the witnesses to write the earlier dates, then he
only took issue with him in one point, but if he restricted them to writing
the latter date (which would be less radical), then he disagreed with him in
(a) Rebbi Yehudah in a Beraisa describes a Sh'tar which contains a date from
the sun-year, which turns out to be a Shabbos or Yom Kipur - as a Sh'tar
Me'uchar (post-dated) which is Kasher.
(b) In any event, the Sh'tar cannot have been written on the given day -
though it might alternatively be a Sh'tar Mukdam (pre-dated), in which case
it would be Pasul (acording to everybody).
(c) It is clear from a Sugya in Makos that we consider the Sh'tar, Me'uchar
rather than Mukdam. We can also prove it from 'Kiyum Sh'taros', which is
only mi'de'Rabbanan - implying that min'ha'Torah, they are Kasher anyway,
because the onus lies on the defendant to prove the Sh'tar Pasul.
(d) The basis for this ruling is a statement by Resh Lakish - who considers
the signatures of witnesses who sign on a Sh'tar as if they had been
verified in Beis-Din.
(a) Rebbi Yossi says Pasul. When Rebbi Yehudah queried him from a similar
Sh'tar which came before him in Tzipori, and which he declared Kasher - he
replied that that case referred to the same case as Rebbi Yehudah was
Rebbi Yehudah - validates a Sh'tar Me'uchar in all of the above cases, since
he holds 'Ein Kosvin Shover', and there is nothing to be afraid of.
(b) Rebbi P'das therefore establishes the Machlokes - by a regular Sh'tar
Me'uchar (where there is no indication in the Sh'tar itself that it was not
written on the day that the loan took place).
(c) Rebbi Yossi differentiates between the two kinds of Sh'tar, rendering
1. ... the former Pasul - because we are afraid that, in a case where the
debtor paid half his debt, and the creditor wrote him a receipt dated on the
day that he paid him, the creditor will eventually produce the same Sh'tar
again, which because it is post-dated (to a date later than that of the
debtor's payment) will enable him to claim that it is a new debt that took
place after the first repayment.
(d) The same will apply, according to Rebbi Yossi - in a case where the
creditor lost his Sh'tar, and the debtor paid in exchange for a receipt
(there too. we are afraid that he will find the Sh'tar, and use it to claim
again, as we just explained).
2. ... the latter Kasher - because, the fact that the date clearly indicates
that the original Sh'tar was Me'uchar, will prevent him from cheating with
(a) Rav Huna B'rei de'Rav Yehoshua attempts to restrict Rebbi Yossi's Din
('Kosvin Shover') to where the debtor paid half - and where the current
dilemma is not the creditor's fault. But in a case where he lost his
Sh'tar - which is negligent on his part, he thinks that Rebbi Yossi will
concede to Rebbi Yehudah that 'Ein Kosvin Shover'.
(b) And we prove this from a second episode where Rav Yitzchak bar Yosef
lent Rebbi Aba money. When the former claimed to have lost the Sh'tar, and
volunteered to write a receipt, the latter quoted Rav and Shmuel - who hold
'Ein Kosvin Shover.
(a) When Rav Yitzchak bar Yosef countered Rav Yitzchak bar Yosef, his
opening words were 'Ma'an Yahiv Lan me'Afra de'Rav u'Shmuel Raminan
be'Aynin' - meaning that he revered Rav and Shmuel to the extent that he
wished they would throw some of the dust from their graves in his eyes.
(b) Rav Yitzchak's counter-argument was - that Rebbi Yochanan and Resh
Lakish (like whom we rule against Rav and Shmuel) hold 'Kosvin Shover'.
(c) Ravin Amar Rebbi Ila'a too holds 'Kosvin Shover'. And we conclude the
Sugya with the argument and counter argument why each one should not have to
look after the Sh'tar. Rava's final word is - that logically, we have to
rule 'Kosvin Shover', because of the principle 'Eved Loveh le'Ish Malveh'
(as we explained Rebbi Yossi earlier).
(a) We learned in the Mishnah in Shevi'is 'Sh'tarei-Chov ha'Mukdamin
Pesulin, ve'ha'Me'ucharin Kesheirin'. The Reisha speaks about a case where
the creditor pre-dated the Sh'tar. A Sh'tar Mukdam which is written on the
current date, only the loan did not take place until later, is subject to a
Machlokes Amora'im in Bava Metzi'a.
(b) Abaye considers such a Sh'tar Mukdam Kasher -because he holds 'Eidav
ba'Chasumav Zachin Lo' (meaning that from the moment the borrower wrote the
Sh'tar, he is Meshabed his property to the creditor, and the signatures
validate the Shibud immediately (in which case it is not a Sh'tar Mukdam at
(c) Rav Hamnuna confines this to a Sh'tar-Chov; a Sh'tar Mekach u'Memkar
Me'uchar is Pasul - because we are afraid that the seller will obtain money
in the interim and redeem his property. The purchaser, claiming that he lost
his Sh'tar, will give the seller a receipt (even according to Rebbi Yehudah,
since there is nothing to lose). Then when the date on the Sh'tar arrives,
he will produce the Sh'tar and claim that he bought the field a second time
after having sold it back to the owner.
(d) A Sh'tar-Chov Me'uchar is not Pasul for the same reason - because the
author of the Mishnah in Shevi'is is Rebbi Yehudah, who holds 'Ein Kosvin
(a) Later, it became customary to write Sh'tarei-Chov Me'ucharin, even
though they would write a Shover. Rav Yeimar (or Yirmiyah mi'Difti)
attributed this to a statement by Rebbi Aba, who instructed his Sofer to
write in the Sh'tarei-Chov Me'ucharin - that it was a Sh'tar Me'uchar (and
as we learned earlier, whenever the suspicious aspect of the date is marked
explicitly in the Sh'tar, there is nothing to fear).
(b) Rav Ashi reconciled a later Minhag still, to write a receipt, with the
fact that they would nevertheless validate a Sh'tar Me'uchar, even without
conforming with Rebbi Aba, by citing Rav Safra - who instructed his Sofer to
insert the date of the Sh'tar Me'uchar in the receipt, and if they did not
know it, to omit the date altogether (thereby removing any reason to
invalidate the Sh'tar).
(c) The creditor is therefore advised - not to make any loans to the debtor
as long as he has that receipt in his possession, because the receipt will
negate any Sh'tar that the creditor produces.
(d) When Ravina asked Rav Ashi (or Rav Ashi, Rav Kahana) why even that
advice was not being adhered to - he replied that Chazal cannot do more than
issue decrees, and those who fail to adhere them must suffer the
