The "valley of vision" (Isa. 22:1) is usually regarded as denoting Jerusalem, which "may be so called," says Barnes (Com. on Isa.), "either (1) because there were several valleys within the city and adjacent to it, as the vale between Mount Zion and Moriah, the vale between Mount Moriah and Mount Ophel, between these and Mount Bezetha, and the valley of Jehoshaphat, the valley of the brook Kidron, etc., without the walls of the city; or (2) more probably it was called the valley in reference to its being compassed with hills rising to a considerable elevation above the city" (Ps. 125:2; comp. also Jer. 21:13, where Jerusalem is called a "valley").
4) Heb. nahal, a wady or water-course (Gen. 26:19; Cant. 6:11).
