(ruins ).

1. A city on the torrent Arnon, the southern point of the territory of Sihon king of the Amorites and afterwards of the tribe of Reuben, ( 2:36 ; 3:12 ; 4:48 ; Joshua 12:2 ; Joshua 13:9 Joshua 13:16 ; Judges 11:26 ; 2 Kings 10:33 ; 1 Chronicles 5:8 ) but later again in possession of Moab. ( Jeremiah 48:19 ) It is the modern Arair , upon the very edge of the precipitous north bank of the Wady Mojeb .
2. Aroer, "that is facing Rahbah" (Rabbah of Ammon), a town built by and belonging to Gad. ( Numbers 32:34 ; Joshua 13:25 ; 2 Samuel 24:5 ) This is probably the place mentioned in ( Judges 11:33 ) which was shown in Jeromes time.
3. Aroer, in ( Isaiah 17:2 ) if a place at all, must be still farther north than either of the two already named.
4. A town in Judah, named only in ( 1 Samuel 30:28 ) perhaps Wady Ararah , on the road from Petra to Gaza.
