1 Samuel 13:5-7

The Philistines mustered a mighty army of 3,000 chariots, 6,000 charioteers, and as many warriors as the grains of sand on the seashore! They camped at Micmash east of Beth-aven. The men of Israel saw what a tight spot they were in; and because they were hard pressed by the enemy, they tried to hide in caves, thickets, rocks, holes, and cisterns. Some of them crossed the Jordan River and escaped into the land of Gad and Gilead. Meanwhile, Saul stayed at Gilgal, and his men were trembling with fear.
