Leviticus 24:20-23

²⁰Wound for wound, eye for eye, tooth for tooth; whatever damage he has done, so let it be done to him.

²¹He who puts a beast to death will have to make payment for it; he who puts a man to death will himself be put to death.

²²You are to have the same law for a man of another nation living among you as for an Israelite; for I am the Lord your God.

²³And Moses said these words to the children of Israel, and they took the man who had been cursing outside the tent-circle and had him stoned. The children of Israel did as the Lord gave orders to Moses.
