Leviticus 24:19-21

New Revised Standard Version, Anglicised

¹⁹ Anyone who maims another shall suffer the same injury in return: ²⁰ fracture for fracture, eye for eye, tooth for tooth; the injury inflicted is the injury to be suffered. ²¹ One who kills an animal shall make restitution for it; but one who kills a human being shall be put to death.
