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.
Aroer, in ( Isaiah 17:2 ) if a place at all, must be still farther north than either of the two already named.
A town in Judah, named only in ( 1 Samuel 30:28 ) perhaps Wady Ararah , on the road from Petra to Gaza.
