Exodus 21:29-30
21:29 But if the ox had the habit of goring, and its owner was warned, and he did not take the necessary precautions, and then it killed a man or a woman, the ox must be stoned and the man must be put to death.
21:30 If a ransom is set for him, then he must pay the redemption for his life according to whatever amount was set for him.
