valley

Boyd’s Bible Dictionary:

Five Hebrew words are rendered vale or valley in the Bible, only one of which seems to imply that broad sweep of land between mountains or hills generally understood by valley
The others imply (1) a narrow ravine, gorge, or glen (Deut. 34:3,63And the south, and the plain of the valley of Jericho, the city of palm trees, unto Zoar. (Deuteronomy 34:3)

(Zechariah 12:11)); (4) a stretch of sloping ground (Deut. 1:77Turn you, and take your journey, and go to the mount of the Amorites, and unto all the places nigh thereunto, in the plain, in the hills, and in the vale, and in the south, and by the sea side, to the land of the Canaanites, and unto Lebanon, unto the great river, the river Euphrates.

Concise Bible Dictionary:

There are few places in Palestine which resemble the valleys of other countries. Two of the words translated “valley” are also translated “plain,” and signify broad plains between the hills. Two other words refer to the narrow dales or ravines through which the streams run in winter, but many of which are dry in summer, now called wadys.
