1 Samuel 13:5-8

13:5 For the battle with Israel the Philistines had amassed 3,000 chariots, 6,000 horsemen, and an army as numerous as the sand on the seashore. They went up and camped at Micmash, east of Beth Aven. 13:6 The men of Israel realized they had a problem because their army was hard pressed. So the army hid in caves, thickets, cliffs, strongholds, and cisterns. 13:7 Some of the Hebrews crossed over the Jordan River to the land of Gad and Gilead. But Saul stayed at Gilgal; the entire army that was with him was terrified. 13:8 He waited for seven days, the time period indicated by Samuel. But Samuel did not come to Gilgal, and the army began to abandon Saul.
