Leviticus 24:19-21

EJ2000(i) 19 And if a man causes a blemish in his neighbour; as he has done, so shall it be done to him; 20 breach for breach, eye for eye, tooth for tooth: as he has caused a blemish in a man, so shall it be done to him again. 21 He that kills an animal shall restore it, but he that kills a man shall be put to death.
