1 Samuel 13:1-8

Saul was thirty years old when he began to reign, and he reigned forty-two years over Israel. Saul chose for himself 3,000 men of Israel; of whom 2,000 were with him in Michmash and in the hill country of Bethel, while 1,000 were with Jonathan at Gibeah of Benjamin. But he sent the rest of the people away, each one to his own tent. Jonathan attacked and defeated the Philistine garrison which was at Geba, and the Philistines heard about it. Then Saul blew the trumpet throughout the land, saying, “Let the Hebrews hear.” All Israel heard that Saul had defeated the Philistine garrison, and also that Israel had become despicable to the Philistines. And the people were summoned to join Saul at Gilgal. Now the Philistines gathered to fight against Israel, 30,000 chariots and 6,000 horsemen, and troops in multitude, like sand on the seashore. They came up and camped at Michmash, east of Beth-aven. When the men of Israel saw that they were in a tight situation (for their troops were hard-pressed), they hid in caves, in thickets, in cellars, and in [dry] cisterns (pits). Also some of the Hebrews had crossed the [river] Jordan to the land of Gad and Gilead. As for Saul, he was still in Gilgal, and all the people followed him, trembling [in fear and anticipation]. Now Saul waited seven days, according to the appointed time which Samuel had set, but Samuel had not come to Gilgal; and the people were scattering away from Saul.
