Deuteronomy 20:15

It was in this way that Israel was to act with towns that were far off; but not with the towns of the Canaanites ("these nations"), which Jehovah gave them for an inheritance. In these no soul was to be left alive; but these nations were to be laid under the ban, i.e., altogether exterminated, that they might not teach the Israelites their abominations and sins (cf. Deu 7:1-4; Deu 12:31). כּל־נשׁמה, lit., every breath, i.e., everything living, by which, however, human beings alone are to be understood (comp. Jos 10:40; Jos 11:11, with Deu 11:14).

This chapter settles the militia, and establishes the laws and ordinances of war, I. Relating to the soldiers. 1. Those must be encouraged that were drawn up to battle (Deu 20:1-4). 2. Those must be dismissed and sent back again whose private affairs called for their attendance at home (Deu 20:5-7), or whose weakness and timidity unfitted them for service in the field (Deu 20:8, Deu 20:9). II. Relating to the enemies they made war with. 1. The treaties they must make with the cities that were far off (Deu 20:10-15). 2. The destruction they must make of the people into whose land they were going (Deu 20:16-18). 3. The care they must take, in besieging cities, not to destroy the fruit-trees (Deu 20:19, Deu 20:20).

20:15 Places described as distant towns were outside the boundaries of the Promised Land.
