Deuteronomy 20:12

If the hostile town, however, did not make peace, but prepared for war, the Israelites were to besiege it; and if Jehovah gave it into their hands, they were to slay all the men in it without reserve ("with the edge of the sword," see at Gen 34:26); but the women and children and all that was in the city, all its spoil, they were to take as prey for themselves, and to consume (eat) the spoil, i.e., to make use of it for their own maintenance.

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).
