Deuteronomy 2:32-35

Then Sihon came out against us, he and all his people, unto battle at Jahaz. And Jehovah our God delivered him up before us; and we smote him, and his sons, and all his people. And we took all his cities at that time, and utterly destroyed every inhabited city, with the women and the little ones; we left none remaining: only the cattle we took for a prey unto ourselves, with the spoil of the cities which we had taken.
