Exodus 21:28-29

“If an ox gores a man or a woman to death, the ox must be stoned and its meat shall not be eaten; but the owner of the ox shall be cleared [of responsibility]. But if the ox has tried to gore on a previous occasion, and its owner has been warned, but has not kept it confined and it kills a man or a woman, the ox shall be stoned and its owner shall be put to death as well.
