Deuteronomy 2:32-35

When Sihon and all his army came out to meet us in battle at Jahaz, the LORD our God delivered him over to us and we struck him down, together with his sons and his whole army. At that time we took all his towns and completely destroyed them—men, women and children. We left no survivors. But the livestock and the plunder from the towns we had captured we carried off for ourselves.
