Exodus 21:28-29

28“Whenever a bull gores a man or a woman to death, the bull must be stoned to death, and its meat may not be eaten. The bull’s owner is free from any liability.

29But if the bull has had the habit of goring, and the owner has been warned but has not kept it confined, and it kills a man or a woman, then the bull must be stoned and its owner must be put to death, too.
