Location
Henry Baker Tristram suggested that "Aroer, which is on the edge of the valley of Arnon" () is the place of modern 'Ara'ir on the north bank of the Wadi Mujib ravine, the biblical Arnon stream, about  from the mouth of the river. The city was still standing in the time of Eusebius. This place was usually described by its situation, in order to distinguish it from other localities of the same name. Biblical mentions
It appears first as having been captured from Moab by the Amorite king Sihon. After the Israelite attack on the Amorites, it was assigned as part of the territory of the tribe of Reuben, whose southern frontier it marked. This is the city mentioned in , with the southern towns, as having been built by the Tribe of Gad before the Tribal allotments of Israel. When Hazael of Aram Damascus took the Transjordan territory from the Kingdom of Israel, Aroer is given as its southern limit. It is clear, from , that the Moabites ultimately recovered it from Israel. In , an Adadah is mentioned. According to Cheyne and Black, arguing partially on the basis of a Septuagint reading of Arouel, this Adadah may in fact be the result of a scribal error, with the text originally reading Ararah, meaning Aroer. According to a prophecy in the Book of Isaiah, "the cities of Aroer" will become forsaken; however, the Septuagint relates this verse to Damascus in Syria, translating as "deserted for ever" (see Isaiah 17:2).
