AROER
1. An ancient city on the north side of the Arnon, in the southern border of the tribe of Reuben, Deuteronomy 2:36; Deuteronomy 1:4; Joshua 13:9. It was in the territory of the Amorites, Joshua 12:2, but seems to have fallen at a later day into the hands of Moab, Jeremiah 48:19. See ARNON.
2. A town in the tribe of God, probably east of Rabbath-Ammon, Joshua 13:25, and perhaps on the Jabbok, 2 Samuel 24:5. It is mentioned in Judges 11:33
3. A town of Judah, to which David sent presents, 1 Samuel 30:28; 1 Chronicles 11:44. Robinson found traces of it about sixteen miles south by west from Hebron.
