Deuteronomy 20:15-19

¹⁵You should do that in all the cities that are far from the land in which you will settle.

¹⁶But in the cities that are in the land that Yahweh our God is giving to you, you must kill all the people and all the animals LIT.

¹⁷You must get rid of them completely. Get rid of the Heth people-group, the Amor people-group, the Canaan people-group, the Periz people-group, the Hiv people-group, and the Jebus people-group; that is what Yahweh our God commanded you to do.

¹⁸If you do not do that, they will teach you to sin against Yahweh our God and do the disgusting things that they do when they worship their gods.

¹⁹When you surround a city for a long time, trying to capture it, do not cut down the fruit trees outside the city. You are allowed to eat the fruit from the trees, but do not get rid of the trees, because they certainly are not RHQ your enemies.
