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; Josh 13:9; Josh 13:16; Judges 11:26; 2Kings 10:33; 1Chronicles 5:8) but later again in possession of Moab. (Jeremiah 48:19) It is the modern Ara’ir, upon the very edge of the precipitous north bank of the Wady Mojeb.
