Deuteronomy 20:10–18

¹⁰If at any time thou come to fight against a city, thou shalt first offer it peace.

¹¹If they receive it, and open the gates to thee, all the people that are therein, shall be saved, and shall serve thee paying tribute.

¹²But if they will not make peace, and shall begin war against thee, thou shalt besiege it.

¹³And when the Lord thy God shall deliver it into thy hands, thou shalt slay all that are therein of the male sex, with the edge of the sword,

¹⁴Excepting women and children, cattle and other things, that are in the city. And thou shalt divide all the prey to the army, and thou shalt eat the spoils of thy enemies, which the Lord thy God shall give thee.

¹⁵So shalt thou do to all cities that are at a great distance from thee, and are not of these cities which thou shalt receive in possession.

¹⁶But of those cities that shall be given thee, thou shalt suffer none at all to live:

¹⁷But shalt kill them with the edge of the sword, to wit, the Hethite, and the Amorrhite, and the Chanaanite, the Pherezite, and the Hevite, and the Jebusite, as the Lord thy God hath commanded thee:

¹⁸Lest they teach you to do all the abominations which they have done to their gods: and you should sin against the Lord your God.
