Arabah
    plain, in the Revised Version of 2 Kings 14:25; Josh. 3:16;
    8:14; 2 Sam. 2:29; 4:7 (in all these passages the A.V. has
    "plain"); Amos 6:14 (A.V. "wilderness"). This word is found in
    the Authorized Version only in Josh. 18:18. It denotes the
    hollow depression through which the Jordan flows from the Lake
    of Galilee to the Dead Sea. It is now called by the Arabs
    el-Ghor. But the Ghor is sometimes spoken of as extending 10
    miles south of the Dead Sea, and thence to the Gulf of Akabah on
    the Red Sea is called the Wady el-Arabah.
