Leviticus 24:17-22

And he that smiteth any man mortally shall surely be put to death. And he that smiteth a beast mortally shall make it good, life for life. And if a man cause a blemish in his neighbor; as he hath done, so shall it be done to him: breach for breach, eye for eye, tooth for tooth; as he hath caused a blemish in a man, so shall it be rendered unto him. And he that killeth a beast shall make it good: and he that killeth a man shall be put to death. Ye shall have one manner of law, as well for the sojourner, as for the home-born: for I am Jehovah your God.
