תלמוד על כתובות 13:9

MISHNAH: Two tame bulls which injured one another; one pays half for the excess damage¹¹⁸Since each owner has to pay damages to the other, in effect only the owner of the bull causing the greater damage has to pay for the excess damage his animal did cause, by the statutory rate of 50% for the tame, 100% for the notorious.. If both are notorious, one pays in full for the excess damage. One tame and one notorious; the notorious over the tame pays in full for the excess damage; the tame over the notorious pays half for the excess damage.
Similarly, two people who injured one another pay in full for the excess damage¹¹⁹Since a human always is notorious (2:10).. A human and a notorious animal, or a notorious animal and a human, one pays in full for the excess damage. A human and a tame animal; the human over the tame pays in full for the excess damage; the tame over the human pays half for the excess damage. Rebbi Akiba says, also a tame animal which injured a human pays the excess damage in full¹²⁰He holds that the rules of Ex. 21 do not apply to damages caused to humans..
A bull worth a mina¹²¹100 denars. which gored a bull worth 200 and the cadaver is not worth anything; he¹²²The owner of the dead bull. It is presumed that the aggressor was tame and the damage be paid from its body (Mishnah 1:5). takes the bull. A bull worth 200 which gored a bull worth 200 and the cadaver is not worth anything; Rebbi Meïr said, about this case it was said¹²³Ex. 21:35.: “They shall sell the living bull and split the proceeds.” Rebbi Jehudah said to him, you upheld “they shall sell the living bull and split the proceeds,” but you did not uphold ¹²³Ex. 21:35.“and also the cadaver they shall split.” What is this? That is a bull worth 200 which gored a bull worth 200 and the cadaver is worth 50 zuz¹²⁴The Babylonian half-šeqel, zūz, is identified with the Roman denar., in which case each owner takes half of the living bull and half from the cadaver¹²⁵Tosephta 3:3; Mekhilta dR.
