1 Samuel 13:9-12

So Saul said, “Bring to me the burnt offering and the peace offerings.” And he offered the burnt offering. As soon as he finished offering the burnt offering, behold, Samuel came; and Saul went out to meet him and to greet him. But Samuel said, “What have you done?” And Saul said, “Because I saw that the people were scattering from me, and that you did not come within the appointed days, and that the Philistines were assembling at Michmash, therefore I said, ‘Now the Philistines will come down against me at Gilgal, and I have not asked the favor of the LORD.’ So I forced myself and offered the burnt offering.”
