Leviticus 24:18-20

¹⁸he that smiteth a beast, yield one in his stead, that is, life for life.

¹⁹If a man giveth a wem to any of his citizens, as he did, so be it done to him;

²⁰he shall restore breaking for breaking, eye for eye, tooth for tooth; what manner wem he gave, he shall be compelled to suffer such a wem.
