Leviticus 24:20

18And he that killeth a beast shall make it good; beast for beast.

19And if a man cause a blemish in his neighbour; as he hath done, so shall it be done to him;

20Breach for breach, eye for eye, tooth for tooth: as he hath caused a blemish in a man, so shall it be done to him again.

21And he that killeth a beast, he shall restore it: and he that killeth a man, he shall be put to death.

22Ye shall have one manner of law, as well for the stranger, as for one of your own country: for I am the LORD your God.
