Leviticus 24:19KJV

17And he that killeth any man shall surely be put to death.

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 .

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