Exodus 21:12-14

¶ He that smiteth a man, so that he die, shall be surely put to death.

And 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.

But if a man come presumptuously upon his neighbour, to slay him with guile; thou shalt take him from mine altar, that he may die.
