1 Samuel 13:5-6

Leeser(i) 5 And the Philistines gathered themselves together to fight with Israel, thirty thousand chariots, and six thousand horsemen, and people as the sand which is on the sea-shore in multitude; and they came up, and encamped in Michmash, eastward from Bethaven. 6 And when the men of Israel saw that they were in a strait, for the people were oppressed, then did the people hide themselves in caves, and in thickets, and in rocks, and in strongholds, and in pits.
