1 Samuel 17:3

And the Philistines stood on a mountain on the one side, and Israel stood on a mountain on the other side: and there was a valley between them.

And there was a valley between them, х wªhagayª' (H1516), the ravine]. 'A close examination of the locality would show, what, indeed, a closer inspection of the text suggests, that the ravine between the two armies was the glen into which the valley contracted in its descent toward the plain of Philistia' (Stanley, 'Sinai and Palestine,' Appendix, sec. 2). [Septuagint, kai ho auloon ana meson autoon, the narrow passage: the glen was between them] (see the note at 1 Samuel 17:52).
