Leviticus 24:17-23 - An Eye For An Eye
17 'And when a man smiteth any soul of man, he is certainly put to death. 18 'And he who smiteth a beast repayeth it, body for body. 19 'And when a man putteth a blemish in his fellow, as he hath done so it is done to him; 20 breach for breach, eye for eye, tooth for tooth; as he putteth a blemish in a man so it is done in him. 21 And he who smiteth a beast repayeth it, and he who smiteth the life of man is put to death; 22 one judgment is to you; as a sojourner so is a native; for I am Jehovah your God.'
23 And Moses speaketh unto the sons of Israel, and they bring out the reviler unto the outside of the camp, and stone him with stones; and the sons of Israel have done as Jehovah hath commanded Moses.
