Deuteronomy 20:12-14

King James Version

¹² And if it will make no peace with thee, but will make war against thee, then thou shalt besiege it:

¹³ And when the Lord thy God hath delivered it into thine hands, thou shalt smite every male thereof with the edge of the sword:

¹⁴ But the women, and the little ones, and the cattle, and all that is in the city, even all the spoil thereof, shalt thou take unto thyself; and thou shalt eat the spoil of thine enemies, which the Lord thy God hath given thee.
