valley
(vāl’ē)
A long, narrow region of low land between ranges of mountains, hills, or other high areas, often having a river or stream running along the bottom. Valleys are most commonly formed through the erosion of land by rivers or glaciers. They also form where large regions of land are lowered because of geological faults.

(1.) Heb. bik’ah, a “cleft” of the mountains (Deut. 8:7; 11:11; Ps. 104:8; Isa. 41:18); also a low plain bounded by mountains, as the plain of Lebanon at the foot of Hermon around the sources of the Jordan (Josh. 11:17; 12:7), and the valley of Megiddo (2 Chr. 35:22). (2.) ‘Emek, “deep;” “a long, low plain” (Job 39:10, 21; Ps. 65:13; Cant. 2:1), such as the plain of Esdraelon; the “valley of giants” (Josh. 15:8), usually translated “valley of Rephaim” (2 Sam. 5:18); of Elah (1 Sam. 17:2), of Berachah (2 Chr. 20:26); the king’s “dale” (Gen. 14:17); of Jehoshaphat (Joel 3:2, 12), of Achor (Josh. 7:24; Isa. 65:10), Succoth (Ps. 60:6), Ajalon (Josh. 10:12), Jezreel (Hos. 1:5). (3.)

(4.) Heb. nahal, a wady or water-course (Gen. 26:19; Cant. 6:11).
