Arnon

Meaning: Swift

the southern boundary of the territory of Israel beyond Jordan, separating it from the land of Moab (Deuteronomy 3:8, 16)

This river (referred to 24 times in the Bible) rises in the mountains of Gilead, and after a circuitous course of about 80 miles through a deep ravine it falls into the Dead Sea nearly opposite Engedi. The stream is almost dry in summer. It later became known as el-Mujeb.

The territory of the Amorites extended from the Arnon to the Jabbok.
