Leviticus 24:18-20

¹⁸And he who killeth the life of a beast shall make it good, life for life.

¹⁹And if a man inflict a blemish on his neighbour, as he hath done, so it shall be done to him:

²⁰Bruise for bruise, eye for eye, tooth for tooth as he hath inflicted a blemish upon a man, it shall be done to him.
