1 Samuel 13:11-12

11But Samuel said, “What have you done?” Saul said, “Since I saw that the people were scattering away from me, and that you did not come within the appointed time, and that the Philistines were assembling at Michmash,

12therefore, I said, ‘Now the Philistines will come down against me at Gilgal, and I have not asked for the Lord’s favor [by making supplication to Him].’ So I forced myself to offer the burnt offering.”
