Meaning
1. ’Emek. This appears to approach more nearly to the general sense of the English word than any other. It is connected with several places.
2. Gai or ge. Of this there is fortunately one example which can be identified with certainty --the deep hollow which compasses the southwest and south of Jerusalem. This identification establishes the ge as a deep and abrupt ravine, with steep sides and narrow bottom.
3. Nachal. This word answers to the Arabic wady, and expresses, as no single English word can, the bed of a stream (often wide and shelving, and like a "valley" in character, which in the rainy season may be nearly filled by a foaming torrent, though for the greater part of the year dry).
4. Bik’ah. This term appears to mean rather a plain than a valley, though so far resembling it as to be enclosed by mountains. It is rendered by "valley" in (34:3; Josh 11:8; Josh 11:17; 12:7; 2Chronicles 35:22; Zechariah 12:11)
5. has-Shefelah. The district to which the name has-Shefelah is applied in the Bible has no resemblance whatever to a valley, but is a broad, swelling tract of many hundred miles in area, which sweeps gently down from the mountains Judah to the Mediterranean. It is rendered "the vale" in (1:7; Joshua 10:40; 1Kings 10:27; 2Chronicles 1:15; Jeremiah 33:13) and "the valley" or "the valleys" in (Joshua 9:1; Josh 11:2; Josh 11:16; 12:8; 15:33; Judges 1:9; Jeremiah 32:44)
