Deuteronomy 20:12-14

New Revised Standard Version, Anglicised

¹² If it does not submit to you peacefully, but makes war against you, then you shall besiege it; ¹³ and when the Lord your God gives it into your hand, you shall put all its males to the sword. ¹⁴ You may, however, take as your booty the women, the children, livestock, and everything else in the town, all its spoil. You may enjoy the spoil of your enemies, which the Lord your God has given you.
