Heb.'arabah, the valley from the Sea of Galilee southward to the Dead Sea (the "sea of the plain," 2 Ki. 14:25; Dt. 1:1, 2:8), a distance of about 70 miles. It is called by the modern Arabs the Ghor. This Hebrew name is found in Authorized Version (Josh. 18:18), and is uniformly used in the Revised Version. Down through the centre of this plain is a ravine, from 200 to 300 yards wide, and from 50 to 100 feet deep, through which the Jordan flows in a winding course. This ravine is called the "lower plain."
The name Arabah is also applied to the whole Jordan valley from Mount Hermon to the eastern branch of the Red Sea, a distance of about 200 miles, as well as to that portion of the valley which stretches from the Sea of Galilee to the same branch of the Red Sea, i.e., to the Gulf of Akabah about 100 miles in all.
