C. F. Keil and Franz Delitzsch on Deuteronomy 20:12-14

Deu 20:12-14

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.
