Deuteronomy 2:37

31 And the LORD said unto me, Behold, I have begun to give Sihon and his land before thee: begin to possess, that thou mayest inherit his land.

32 Then Sihon came out against us, he and all his people, to fight at Jahaz.

33 And the LORD our God delivered him before us; and we smote him, and his sons, and all his people.

34 And we took all his cities at that time, and utterly destroyed the men, and the women, and the little ones, of every city, we left none to remain:

35 Only the cattle we took for a prey unto ourselves, and the spoil of the cities which we took.

36 From Aroer, which is by the brink of the river of Arnon, and from the city that is by the river, even unto Gilead, there was not one city too strong for us: the LORD our God delivered all unto us:

37 Only unto the land of the children of Ammon thou camest not, nor unto any place of the river Jabbok, nor unto the cities in the mountains, nor unto whatsoever the LORD our God forbad us.
