Leviticus 24:17-23 - An Eye For An Eye
17 And he who kills any man shall surely be put to death. 18 And he who kills an animal shall make it good, animal for animal. 19 And if a man causes a blemish in his neighbor, as he has done, so shall it be done to him: 20 break for break, eye for eye, tooth for tooth. As he has caused a blemish in a man, so shall it be done to him. 21 And he who kills an animal shall restore it. And he who kills a man shall be put to death. 22 One judgment shall be for you whether an alien or a native; for I am Jehovah your God.
23 And Moses spoke to the sons of Israel that they should bring the despiser outside the camp, and stone him with stones. And the sons of Israel did as Jehovah commanded Moses.
