Arnon: 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 twenty-four 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 is now called el-Mujeb. The territory of the Amorites
extended from the Arnon to the Jabbok.
