Exodus 21:12-15

12He that smiteth a man, so that he dieth, shall surely be put to death. 13And if a man lie not in wait, but God deliver him into his hand; then I will appoint thee a place whither he shall flee. 14And if a man come presumptuously upon his neighbor, to slay him with guile; thou shalt take him from mine altar, that he may die.

15And he that smiteth his father, or his mother, shall be surely put to death.
