Deuteronomy 20:15 DBY

¹³  and when Jehovah thy God delivereth it into thy hand, thou shalt smite every male thereof with the edge of the sword:

¹⁴  only the women, and the little ones, and the cattle, and all that shall be in the city, all the spoil thereof, shalt thou take as booty for thyself; and thou shalt eat the spoil of thine enemies, which Jehovah thy God giveth thee

¹⁵  Thus shalt thou do unto all the cities that are very far off from thee, which are not of the cities of these nations.

¹⁶  But of the cities of these peoples which Jehovah thy God giveth thee for an inheritance, thou shalt save alive nothing that breatheth,

¹⁷  but shalt utterly devote them to destruction, the Hittites and the Amorites, the Canaanites and the Perizzites, the Hivites and the Jebusites, as Jehovah thy God hath commanded thee;
