2 Samuel 5:18

Then the Philistines yet again came up and spread themselves out in the valley of Rephaim.

from Aram, Moab, the sons of Ammon, the Philistines, Amalek, and from the spoil of Hadadezer, son of Rehob, king of Zobah.

And the Philistines were at war again with Israel, so David went down and his servants with him; and as they fought against the Philistines, David became weary.

Then three of the thirty chief men went down and came to David in the harvest time to the cave of Adullam, while the troop of the Philistines was camping in the valley of Rephaim.

And it will be even like the reaper gathering the standing grain, As his arm harvests the ears of grain, Or it will be like one gleaning ears of grain In the valley of Rephaim.
