Exodus 21:29-30

29But if the ox was accustomed to push with his horn in time past, and it hath been testified to his owner, and he hath not restrained him, but that he hath killed a man or a woman; the ox shall be stoned, and his owner also shall be put to death. 30If there shall be laid on him a sum of money, then he shall give for the ransom of his life whatever is laid upon him.
