1 Samuel 13:5-8

5The Philistines assembled to fight Israel, with three thousand chariots, six thousand charioteers, and soldiers as numerous as the sand on the seashore. They went up and camped at Mikmash, east of Beth Aven. 6When the Israelites saw that their situation was critical and that their army was hard pressed, they hid in caves and thickets, among the rocks, and in pits and cisterns. 7Some Hebrews even crossed the Jordan to the land of Gad and Gilead. Saul remained at Gilgal, and all the troops with him were quaking with fear. 8He waited seven days, the time set by Samuel; but Samuel did not come to Gilgal, and Saul’s men began to scatter.
