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