Yerushalmi Bava Kamma 4:2 ירושלמי בבא קמא ד׳:ב׳

MISHNAH: A bull which is notorious for its kind but not notorious for other species, notorious for humans but not notorious for animals, notorious for small ones but not notorious for large ones, pays full damages for what it is notorious for, but half damages for what it is not notorious for. They asked before Rebbi Jehudah: If it was notorious on the Sabbath but not on weekdays? He answered, it pays full damages on Sabbaths but half damages on weekdays. When does it revert to be tame? If it changed its ways for three Sabbath days²⁸Following R. Jehuda’s opinion in Mishnah 2:6..

HALAKHAH: “A bull which is notorious for its kind,” etc. After it killed one human, is it not notorious²⁹Any animal which killed “a man or a woman” has to be killed (Ex. 21:28). How can such an animal ever become notorious after three times if it is killed after the first time?? Rav said, if it killed three Gentiles³⁰Who are not subsumed under the appellation “man or woman”. Babli 41a, in the name of Rav Sheshet.. Rebbi Yose ben Ḥanina said, if it pursued three times and it was estimated that every pursuit was for goring³¹For endangering humans, an animal may become notorious for trying three times..

³²Halakhah 2:6, Notes 90–96. If it was let out the first day and gored bulls, the second it gored dogs, the third it gored pigs: would it be declared a notorious bull for three different kinds on three days? If it was let out the first day and gored, the second day it was not let out, the third day it was let out and gored, we come to the disagreement between Rav Ada bar Aḥawa and Rav Huna, who disagreed: A menstruating woman checked herself the first day and found herself impure. The second day she did not check. On the third day she checked and found herself impure. Rav Ada bar Aḥawa said in the name of Rav: she certainly is niddah. Rav Huna said in the name of Rav: it is doubtful whether she is niddah. Rav Huna said, I was there at the beginning, I was there at the end, and I was there in the middle when Rav was asked, and he said, it is doubtful. Rav was asked and he said, it is certain; then he reversed himself and said, it is doubtful. Rav Ada bar Aḥawa was only there when he said, it is certain.

Rav Jeremiah said in the name of Rav: Practice follows Rebbi Meïr for the tame animal and Rebbi Jehudah for testimony.

We wanted to ask: what is the reason of Rebbi Jehudah³³He accepts that a bull may be notorious only for the Sabbath. Is it reasonable to expect animals to change their behavior according to a human calendar?? Because it sees us dressed³⁴E reads מניין נקיין, a misspelling for מָנִין נְקִיִין “clean garments”. Quoted in Hebrew translation by Tosaphot 37a s.v. הרי; explaining that the bull does not recognize its master and attendants wearing Sabbath clothing. cleanly, it changes its behavior.
