Deuteronomy 20:11-20

11 And it shall be, if it make thee an answer of peace and open unto thee, then it shall be that all the people who are found therein shall be tributaries unto thee, and they shall serve thee.
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.
15 Thus shalt thou do unto all the cities which are very far off from thee, which are not of the cities of these nations.
16 But of the cities of these people which the LORD thy God doth give thee for an inheritance, thou shalt save alive nothing that breatheth,
17 but thou shalt utterly destroy them, namely: the Hittites, and the Amorites, the Canaanites, and the Perizzites, the Hivites, and the Jebusites, as the LORD thy God hath commanded thee,
18 that they teach you not to do according to all their abominations which they have done unto their gods, so ye should sin against the LORD your God.
19 "When thou shalt besiege a city a long time, in making war against it to take it, thou shalt not destroy the trees thereof by forcing an ax against them, for thou mayest eat of them; and thou shalt not cut them down to employ them in the seige, for the tree of the field is man's life.
20 Only the trees which thou knowest are not trees for meat, thou shalt destroy and cut them down; and thou shalt build bulwarks against the city that maketh war with thee, until it be subdued.
