1 Samuel 17:3

A valley between them. The Valley of Elah has a wadi running through the center called the Wadi es-Sant spoken of in this verse as a “valley,” Heb. gaye’. This is quite different from the “valley,” Heb. ‘emeq, of Elah (v. 2). The first Hebrew word is used of a ravine watered by a torrent during the rainy season, the latter, of a wide fertile valley. This gaye’ was well-nigh impassable except at certain spots, and in this respect similar to the wadi in front of Michmash (see on ch. 14:4-10). Saul and his army encamped in the hills on the eastern side of this gaye’, and the Philistines fortified the hills to the west (see 1 Chron. 11:13).
