Barnes' Notes
To the dwelling of Ar - Ar (compare Numbers 21:28; Isaiah 15:1) was on the bank of the Arnon, lower down the stream than where the Israelites crossed. Near the spot where the upper Arnon receives the tributary Nahaliel Numbers 21:19, there rises, in the midst of the meadow-land between the two torrents, a hill covered with the ruins of the ancient city (Joshua 13:9, Joshua 13:16; compare Deuteronomy 2:36).
