Exodus 21:28 - Matthew Poole's English Annotations on the Holy Bible

Under which you are to understand any other creatures of like nature which hurt a man in such a dangerous manner, whether with their horns, or teeth, or feet; but he mentions only the ox or bull, and his goring with his horn, because this is most frequently done. Ox shall be stoned; partly, to prevent future mischiefs from that creature; partly, to punish its master for his negligence in not keeping it in; and principally, for man's admonition, for whom seeing the beasts were made, it is not strange nor unjust if it be destroyed for man's good. God would hereby show that he would not, and men should not, spare a wilful murderer. His flesh shall not be eaten; both because it was forbidden food, its blood being not let out; and for the punishment of the owner, who was hereby hindered from the sale of it, to beget in all the greater detestation of murderers, when they observe the poor beast upon this account accursed, and therefore not to be touched or tasted.
