1 Samuel 13

11 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, 12 I said, ‘Now the Philistines will come down against me at Gilgal, and I have not sought the favor of the Lord.’ So I forced myself, and offered the burnt offering."
