Deuteronomy 20:15-19

¹⁵Thus thou shalt do to all the cities, that be full far from thee, and be not of these (nigh) cities which thou shalt take into possession. (Thus thou shalt do, to all the cities that be far away from thee, but not to the cities that be near, which thou shalt take for a possession.)

¹⁶But of these cities that shall be given to thee, thou shalt not suffer any to live, but thou shalt slay by the sharpness of sword; (But in these cities that shall be given to thee by the Lord, thou shalt not allow anyone to remain alive, but thou shalt kill them all by the sharpness of the sword;)

¹⁷that is to say, Hittites, and Amorites, and Canaanites, and Perizzites, and Hivites, and Jebusites, as thy Lord God hath commanded to thee;

¹⁸lest peradventure they teach you to do all the abominations, which they have wrought (un)to their gods, and ye do sin against your Lord God (or and then ye sin against the Lord your God).

¹⁹When thou hast besieged a city by long time, and thou hast compassed it with strongholds that thou overcome it, thou shalt not cut down the trees, of which men may eat/of which fruit may be eaten, neither thou shalt waste the country(side) about with axes; for it is a tree, and not a man, neither it may increase the number of fighters against thee. (When thou hast besieged a city for a long time, and thou hast surrounded it with strongholds so that thou can overcome it, thou shalt not cut down the trees, from which men can eat or whose fruit can be eaten, nor shalt thou destroy all the countryside about with axes; for it is a tree, and not a man, and it cannot increase the number of fighters against thee.)
