Arnon

A river in the area east of the Jordan River. The Arnon is known today as Wadi el-Mojib. The river runs from east to west through a canyon with walls 457 meters (1,500 feet) high into the Dead Sea.

At the time of the Israelite conquest of Canaan, the gorge served as a natural border between Moab to the south and the Ammonite kingdoms to the north (Numbers 21:13–15).

After the division of the land under Joshua, the river Arnon became the southern boundary of Reuben’s territory (Deuteronomy 3:12, 16; Joshua 13:16).
