1 Samuel 13:11-12

And Samuel said, What hast thou done? And Saul said, Because I saw that the people were scattered from me, and that thou camest not within the days appointed, and that the Philistines assembled themselves together at Michmash; therefore said I, Now will the Philistines come down upon me to Gilgal, and I have not entreated the favor of Jehovah: I forced myself therefore, and offered the burnt-offering.
