1 Samuel 13:5-18
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-a'ven. When the men of Israel saw that they were in straits (for the people were hard pressed), the people hid themselves in caves and in holes and in rocks and in tombs and in cisterns, or crossed the fords of the Jordan to the land of Gad and Gilead. Saul was still at Gilgal, and all the people followed him trembling.
He waited seven days, the time appointed by Samuel; but Samuel did not come to Gilgal, and the people were scattering from him. So Saul said, "Bring the burnt offering here to me, and the peace offerings." And he offered the burnt offering. As soon as he had finished offering the burnt offering, behold, Samuel came; and Saul went out to meet him and salute him.
Samuel said, "What have you done?" And Saul said, "When I saw that the people were scattering from me, and that you did not come within the days appointed, and that the Philistines had mustered at Michmash, I said, `Now the Philistines will come down upon me at Gilgal, and I have not entreated the favor of the LORD'; so I forced myself, and offered the burnt offering."
And Samuel said to Saul, "You have done foolishly; you have not kept the commandment of the LORD your God, which he commanded you; for now the LORD would have established your kingdom over Israel for ever. But now your kingdom shall not continue; the LORD has sought out a man after his own heart; and the LORD has appointed him to be prince over his people, because you have not kept what the LORD commanded you."
And Samuel arose, and went up from Gilgal to Gib'e-ah of Benjamin. And Saul numbered the people who were present with him, about six hundred men. And Saul, and Jonathan his son, and the people who were present with them, stayed in Geba of Benjamin; but the Philistines encamped in Michmash. And raiders came out of the camp of the Philistines in three companies; one company turned toward Ophrah, to the land of Shu'al, another company turned toward Beth-hor'on, and another company turned toward the border that looks down upon the valley of Zebo'im toward the wilderness.
