Deuteronomy 2:30-37

30But Sihon king of Heshbon would not let us pass by him: for the LORD thy God hardened his spirit, and made his heart obstinate, that he might deliver him into thy hand, as at this day. 31And the LORD said unto me, Behold, I have begun to deliver up Sihon and his land before thee: begin to possess, that thou mayest inherit his land. 32Then Sihon came out against us, he and all his people, unto battle at Jahaz. 33And the LORD our God delivered him up before us; and we smote him, and his sons, and all his people. 34And 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: 35only the cattle we took for a prey unto ourselves, with the spoil of the cities which we had taken. 36From Aroer, which is on the edge of the valley of Arnon, and from the city that is in the valley, even unto Gilead, there was not a city too high for us: the LORD our God delivered up all before us: 37only to the land of the children of Ammon thou camest not near; all the side of the river Jabbok, and the cities of the hill country, and wheresoever the LORD our God forbade us.
