Exodus 21:28

If an ox gore. To establish as firmly as possible the principle of the sacredness of human life, Moses takes up in vs. 28-32 injuries caused by domestic animals. Echoing the declaration already made to Noah (Gen. 9:5), the ox must be killed, but the owner is “clear” (RSV). Not being killed in the manner required, the animal might not be eaten. Furthermore, the animal was under a curse. According to rabbinical expositors it was not even lawful to sell the carcass to the Gentiles. By being “stoned” to death, the ox suffered the same penalty that would have been imposed upon a human murderer.
