Deuteronomy 2:32-36

So Sihon and his entire army confronted us in battle at Jahaz. GOD handed him, his sons, and his entire army over to us and we utterly crushed them. While we were at it we captured all his towns and totally destroyed them, a holy destruction—men, women, and children. No survivors. We took the livestock and the plunder from the towns we had captured and carried them off for ourselves. From Aroer on the edge of the Brook Arnon and the town in the gorge, as far as Gilead, not a single town proved too much for us; GOD, our God, gave every last one of them to us.
