Deuteronomy 2:32-35

“Then Sihon with all his people came out to meet us in battle at Jahaz. The LORD our God delivered him over to us, and we defeated him with his sons and all his people. So we captured all his cities at that time and utterly destroyed the men, women and children of every city. We left no survivor. We took only the animals as our booty and the spoil of the cities which we had captured.
