Deuteronomy 2:36-37

“The LORD our God also helped us conquer Aroer on the edge of the Arnon Gorge, and the town in the gorge, and the whole area as far as Gilead. No town had walls too strong for us. However, we avoided the land of the Ammonites all along the Jabbok River and the towns in the hill country—all the places the LORD our God had commanded us to leave alone.
