Deuteronomy 2:36-37

From Aroer on the edge of the valley of the Arnon and from the town in the valley as far as Gilead, no town was strong enough to keep us out; the Lord our God gave them all into our hands: But you did not go near the land of the children of Ammon, that is, all the side of the river Jabbok or the towns of the hill-country, wherever the Lord our God had said we were not to go.
