Deuteronomy 20:10–18

¹⁰When thou approachest unto a city to fight against it, thou shalt proclaim peace unto it. ¹¹And it shall be, if it make thee answer of peace, and open unto thee, then all the people that are found therein shall be tributaries unto thee, and they shall serve thee. ¹²And if it will not make peace with thee, but will make war with thee, then thou shalt besiege it; ¹³and when Jehovah thy God delivereth it into thy hand, thou shalt smite every male thereof with the edge of the sword: ¹⁴only 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 ¹⁵Thus shalt thou do unto all the cities that are very far off from thee, which are not of the cities of these nations. ¹⁶But of the cities of these peoples which Jehovah thy God giveth thee for an inheritance, thou shalt save alive nothing that breatheth, ¹⁷but 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; ¹⁸that they teach you not to do according to all their abominations, which they have done unto their gods, so that ye sin against Jehovah your God.
