1 Samuel 13:8

4 And all Israel heard the news: “Saul has attacked an outpost of the Philistines, and now Israel has become a stench to the Philistines!” Then the people were summoned to join Saul at Gilgal.

5 Now the Philistines assembled to fight against Israel with three thousand chariots, six thousand horsemen, and troops as numerous as the sand on the seashore. They went up and camped at Michmash, east of Beth-aven.

6 Seeing that they were in danger because their troops were hard-pressed, the men of Israel hid in caves and thickets, among the rocks, and in cellars and cisterns.

7 Some Hebrews even crossed the Jordan into the land of Gad and Gilead. Saul, however, remained at Gilgal, and all his troops were quaking in fear.

8 And Saul waited seven days for the time appointed by Samuel, but Samuel did not come to Gilgal, and the troops began to desert Saul.

9 So he said, “Bring me the burnt offering and the peace offerings.” And he offered up the burnt offering.

10 Just as he finished offering the burnt offering, Samuel arrived, and Saul went out to greet him.

11 “What have you done?” Samuel asked. And Saul replied, “When I saw that the troops were deserting me, and that you did not come at the appointed time and the Philistines were gathering at Michmash,

12 I thought, ‘Now the Philistines will descend upon me at Gilgal, and I have not sought the favor of the LORD.’ So I felt compelled to offer the burnt offering.”
