1 Samuel 13:9-12

9And Saul said, Bring hither to me the burnt-offering and the peace-offerings. And he offered up the burnt-offering.

10And it came to pass, as soon as he had ended offering up the burnt-offering, behold, Samuel came; and Saul went out to meet him, that he might salute him.

11And Samuel said, What hast thou done? And Saul said, Because I saw that the people were scattered from me, and that thou didst not come within the days appointed, and that the Philistines were assembled at Michmash,

12I said, The Philistines will come down now upon me to Gilgal, and I have not made supplication to Jehovah; and I forced myself, and offered up the burnt-offering.
