Deuteronomy 20:12-14

Revised Standard Version

¹² But if it makes no peace with you, 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 but the women and the little ones, the cattle, and everything else in the city, all its spoil, you shall take as booty for yourselves; and you shall enjoy the spoil of your enemies, which the Lord your God has given you.
