Deuteronomy 2:36-37

We defeated Aroer on the edge of the Arnon Ravine, and we defeated the town in the ravine, and even as far as Gilead. No town was too strong for us; the LORD our God gave us all of them. But you did not go near the land of the Ammonites, on the shores of the Jabbok River, or the towns in the mountains, as the LORD our God had commanded.
