פירוש על שמות 21:28

וכי יגח שור AND IF AN OX THRUST — This law applies to an ox as well to any other cattle, wild beast or fowl, but Scripture mentions the ox, because it speaks of what usually occurs (Bava Kamma 54b).

וכי יגח שור את איש, If an ox gore a man, etc. The apparently superfluous word את is explained in Sanhedrin 79. If Shimon intended to kill Reuven but killed Levi instead he is guilty of murder since he intended to murder someone. The words את איש mean any man, even one other than the target. This applies only if the original target had been a human being; if one intended to kill an animal and killed a human being instead, the killer is not culpable for murder (compare Sanhedrin 78).

סקול יסקל השור, according to the plain meaning the offending ox will be stoned to death.
