Mount of the valley
Mount of the valley [EBD]
(Josh. 13:19), a district in the east of Jordan, in the territory of Reuben. The "valley" here was probably the Ghor or valley of the Jordan, and hence the "mount" would be the hilly region in the north end of the Dead Sea. (See ZARETH-SHAHAR »3874.)
MOUNT OF THE VALLEY [ISBE]
MOUNT OF THE VALLEY - Zereth-shahar is said to be situated in or on the "mount of the valley" (behar ha`emeq (Josh 13:19)). Cheyne (EB, under the word) says "i.e. on one of the mountains East of the Jordan valley (compare Josephus 13 27), and not impossibly on that described at length in BJ, VII, vi, 1-3." To the Northwest of this mountain is Wady ec-Cara, wherein there may be a reminiscence of Zereth-shahar. There is no certainty.
