Bava Kama 45
1) AN OX THAT IS SENTENCED TO STONING
(a) (Mishnah): Reuven's ox was being brought out to be
stoned; he made it Hekdesh - it is not Hekdesh; if he
slaughtered it, the meat is forbidden.
(b) Before a verdict was reached, if he made it Hekdesh, it
is Hekdesh; if he slaughtered it, the meat is permitted.
(c) If he gave it over to a free watchman, borrower, paid
watchman or renter - they are as the owner: a Mu'ad pays
full damage, a Tam pays half-damage.
(d) (Gemara - Beraisa): Reuven's ox killed - before the final
verdict, if he sold it, it is sold; if he made it
Hekdesh, it is Hekdesh; if he slaughtered it, the meat is
permitted; if the watchman returned it to Reuven's house,
it is considered returned;
1. After the verdict (if Reuven did these things) - it
is not sold, it is not Hekdesh, the meat is
forbidden; if the watchman returned it, it is not
considered returned.
2. R. Yakov says, if the watchman returned it, it is
considered returned.
(e) Suggestion: Chachamim say that a watchman cannot return
something deposited by him after it became forbidden to
benefit from (rather, he must pay); R. Yakov says, he
can.
(f) Rejection (Rabah): All agree, one can return something
that became forbidden to benefit from;
1. [Version #1 (Rashi): If that was the argument,
Chachamim should hold that one may not return
Chametz after Pesach (but they do not).]
2. [Version #2 (Tosfos): If that was the argument, the
argument (here) should have been taught regarding
Chametz on Pesach (so we could not think they argue
on something else).]
(g) Rather, they argue whether Beis Din can sentence an ox
that is not there.
1. Chachamim say they may not sentence an ox in its
absence - Reuven can say, you made me lose my ox -
had you returned it to me, I would have hid it, it
would not have been sentenced;
2. R. Yakov says, an ox may be sentenced in its absence
- in any case, it would have been sentenced.
(h) Question: From where do Chachamim learn?
(i) Answer: "The ox will be stoned, and also the owner will
die" - execution of an ox is as execution of the owner;
1. Just as we only sentence a man when he is present,
also by an ox.
2. R. Yakov says, this only applies to a man, who can
make claims - it is unreasonable to learn this by an
ox!
2) THE RESPONSIBILITY OF WATCHMEN
(a) (Mishnah): If he gave the ox to a free watchman, a
borrower,...
(b) (Beraisa): Four watchmen are in place of the owner: a
free watchman, a borrower, a paid watchman, and a renter.
1. If the animal is Tam - if it kills, it is killed,
Kofer is not paid;
2. If the animal is Mu'ad - if it kills, it is killed,
Kofer is paid;
i. The watchman must compensate the owner for the
loss of his ox, except for a free watchman.
(c) Question: What is the case?
1. Suggestion: If he guarded the ox - no watchman
should have to compensate the owner!
2. Suggestion: If he did not guard the ox - even a free
watchman must repay the value!
(d) Answer: The case is, he guarded it poorly.
1. This is enough for a free watchman, not for other
watchmen.
(e) Question: Who is the Tana of the Beraisa?
1. Suggestion: If as R. Meir, who says that a renter is
as a free watchman - also a renter should be exempt
from returning the value of the ox!
45b---------------------------------------45b
2. Suggestion: If as R. Yehudah, who says that a renter
is as a paid watchman - all should be exempt from
Kofer by a Mu'ad (he holds that a poor guarding
suffices for a Mu'ad)!
(f) Answer #1 (Rav Huna bar Chinena): The Beraisa is R.
Elazar, who says that a Mu'ad cannot be guarded, it must
be killed;
1. Regarding a renter, he holds as R. Yehudah, he is as
a paid watchman.
(g) Answer #2 (Abaye): Really he holds as R. Meir, as Rabah
bar Avuha switches their opinions.
1. (Rabah bar Avuha): R. Meir says, a renter is as a
paid watchman; R. Yehudah says, he is as a free
watchman.
(h) (R. Elazar): Reuven handed his ox over to Shimon, a free
watchman. If it damaged, Shimon is liable; if it was
damaged, he is exempt.
(i) Question: What is the case?
1. If he accepted to guard it - he should be liable
even if it is damaged!
2. If he did not accept to guard it - he should be
exempt even if it damaged!
(j) Answer (Rava): Really, he accepted to guard it - the case
is, he knew it was a gorer.
1. He expected to have to guard it from damaging - he
did not expect to have to guard it from being
damaged (since animals are afraid of it)!
1) HOW WELL MUST ONE GUARD AN ANIMAL?
(a) (Mishnah - R. Meir): Reuven tied his ox with a rope, or
locked (a gate) in front of properly, and it escaped and
damaged - he is liable, whether it is Tam or Mu'ad;
(b) R. Yehudah says, a Tam is liable, a Mu'ad is exempt - "If
he will not guard it", and this is guarded!
(c) R. Elazar says, a Mu'ad cannot be guarded, it must be
killed.
(d) (Gemara) Question: What is R. Meir's reason?
(e) Answer: He holds, people normally do not guard their
oxen; the Torah said that a Tam must pay - it requires a
minimal guarding. By Mu'ad it says "If he will not guard
it", that it must be guarded well; we learn Tam (from a
Gezeirah Shavah "Yigach-Yigach") from Mu'ad.
1. R. Yehudah holds, people normally guard their oxen
(minimally); the Torah said that a Tam must pay - it
must be guarded well. By Mu'ad it says "If he will
not guard it", also saying that is must be guarded
well - since this is a second verse coming to
include the same thing, it really comes to exclude,
i.e. a poor guarding suffices for a Mu'ad.
i. Question: We should learn Tam from Mu'ad,
through the Gezeirah Shavah!
ii. By Mu'ad it says "If he will not guard it" - a
minimal guarding is not enough for anything
else.
iii. Question: But we need the verse to teach that
one who did not guard it is liable!
iv. Answer: It could have said "If he will not
guard"; "it" is extra, to say that a minimal
guarding only suffices for a Mu'ad.
(f) (Beraisa - R. Eliezer ben Yakov): A minimal guarding
suffices for both Tam and Mu'ad.
1. Question: How does he learn?
2. Answer: He learns that a minimal guarding suffices
for a Mu'ad - as R. Yehudah;
i. He learns Tam from Mu'ad from the Gezeirah
Shavah - as R. Meir.
(g) (Rav Ada bar Ahavah): R. Yehudah only exempts the
additional payment of a Mu'ad side with a minimal
guarding, not the half-damage that a Tam pays.
(h) (Rav): An ox Mu'ad to gore with the right horn is not
Mu'ad to gore with the left horn.
(i) Question: (Rav cannot teach about paying half or full
damage - this follows simply from a Mishnah (Mu'ad for
animals is not Mu'ad for people)! Surely, he came to
teach about how well it must be guarded.) As whom does
Rav hold?
1. If as R. Meir - but he holds that both Tam and Mu'ad
need a proper guarding!
2. If as R. Yehudah - even the right horn has both a
Tam and Mu'ad side (so he could have taught about
the levels of guarding the right horn alone)!
(j) Answer: Really, he holds as R. Yehudah; Rav does not hold
as Rav Ada bar Ahavah;
1. This is the only case in which R. Yehudah holds that
a Mu'ad has a Tam side.
