1 Samuel 13:1-6 ESV
Saul lived for one year and then became king, and when he had reigned for two years over Israel, Saul chose three thousand men of Israel. Two thousand were with Saul in Michmash and the hill country of Bethel, and a thousand were with Jonathan in Gibeah of Benjamin. The rest of the people he sent home, every man to his tent. Jonathan defeated the garrison of the Philistines that was at Geba, and the Philistines heard of it. And Saul blew the trumpet throughout all the land, saying, “Let the Hebrews hear.” And all Israel heard it said that Saul had defeated the garrison of the Philistines, and also that Israel had become a stench to the Philistines. And the people were called out to join Saul at Gilgal.
And the Philistines mustered to fight with Israel, thirty thousand chariots and six thousand horsemen and troops like the sand on the seashore in multitude. They came up and encamped in Michmash, to the east of Beth-aven. When the men of Israel saw that they were in trouble (for the people were hard pressed), the people hid themselves in caves and in holes and in rocks and in tombs and in cisterns
