Exodus 21:28-29

28“When an ox gores a man or a woman to death, the ox must be stoned, and its meat may not be eaten, but the ox’s owner is innocent.

29However, if the ox was in the habit of goring, and its owner has been warned yet does not restrain it, and it kills a man or a woman, the ox must be stoned, and its owner must also be put to death.
