ARNON(Ἀρνὠν, LXX.: Wady-el-Môjib), a river which separates Trans-Jordanic Palestine from Moab. (Num.21.13, 26; Deut. 2.24, 3.8, 16; Josh. 12.1; Isa. 16.2; Jer. 48.20.) Its principal source is a little to the NE. of Katrane (Burkhardt, p. 373; comp. J. AJ), whence it pursues a circuitous course into the Dead Sea, flowing in a rocky bed, which in summer is almost dried up, but huge masses of rock torn from the banks mark its impetuosity during the rainy season. (Robinson, Palestine, vol. ii. pp. 206, 213, 569; Irby and Mangles, p. 461.)
