1 Samuel 13:5-7

5Now the Philistines assembled to fight against Israel with three thousand1 chariots, six thousand horsemen, and troops as numerous as the sand on the seashore. They went up and camped at Michmash, east of Beth-aven.

6Seeing that they were in danger because their troops were hard-pressed, the men of Israel hid in caves and thickets, among the rocks, and in cellars and cisterns. 7Some Hebrews even crossed the Jordan into the land of Gad and Gilead. Saul, however, remained at Gilgal, and all his troops were quaking in fear.
