Leviticus 24:19-21

New Catholic Bible

¹⁹ When a man wounds a neighbor, whatever he has done shall be done to him: ²⁰ broken bone for broken bone, eye for an eye, tooth for a tooth. In whatever way he wounded another, so it shall be done to him. ²¹ He who kills an animal shall make restitution and he who kills a man shall be put to death.
