1 Samuel 13:12-16

I thought, ‘Now the Philistines will come down against me at Gilgal, and I have not asked the favor of the Lord.’ So I worked up the courage and offered the burnt offering.”

But Samuel said to Saul, “You have acted foolishly! You have not kept the commandment of the Lord your God, which He commanded you, for the Lord would now have established your kingdom over Israel forever.

But now your kingdom shall not endure. The Lord has sought for Himself a man after His own heart, and the Lord has appointed him ruler over His people, because you have not kept what the Lord commanded you.”

Then Samuel set out and went up from Gilgal to Gibeah of Benjamin. And Saul counted the people who were present with him, about six hundred men.

Now Saul, his son Jonathan, and the people who were present with them were staying in Geba of Benjamin while the Philistines camped at Michmash.
