When all Israel heard that Saul had defeated the garrison of the Philistines, and also that Israel had become odious to the Philistines, the people were called out to join Saul at Gilgal.
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 at Michmash, to the east of Beth-aven.

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."
Samuel said to Saul, "You have done foolishly; you have not kept the commandment of the Lord your God, which he commanded you. The Lord would have established your kingdom over Israel forever,
but now your kingdom will not continue; the Lord has sought out a man after his own heart; and the Lord has appointed him to be ruler over his people, because you have not kept what the Lord commanded you."
And Samuel left and went on his way from Gilgal. The rest of the people followed Saul to join the army; they went up from Gilgal toward Gibeah of Benjamin. Saul counted the people who were present with him, about six hundred men.
