Meaning
Arnon (roaring), the river or torrent which formed the boundary between Moab and the Amorites, on the north of Moab, (Num 21:13; Num 21:14; Num 21:24; Num 21:26; Judges 11:22) and afterwards between Moab and Israel (Reuben). (Deut 2:24; Deut 2:36; Deut 3:8; Deut 3:12; Deut 3:16; 4:48; Josh 12:1; Josh 12:2; Josh 13:9; Josh 13:16; Jude 11:13; Jude 11:26) There can be no doubt that the Wady el-Mojeb of the present day is the Arnon. Its principal source is near Katrane, on the Haj route.
