Exodus 21:29-30

29But if the ox tended to thrust with its horn in times past, and it has been made known to his owner, and he has not kept it confined, so that it has killed a man or a woman, the ox shall be stoned and its owner also shall be put to death.

30If there is imposed on him a sum of money, then he shall pay to redeem his life, whatever is imposed on him.
