1 Samuel 13:8-14

And he tarried seven days, according to the set time that Samuel had appointed: but Samuel came not to Gilgal; and the people were scattered from him. And Saul said, Bring hither the burnt-offering to me, and the peace-offerings. And he offered the burnt-offering. And it came to pass that, as soon as he had made an end of offering the burnt-offering, behold, Samuel came; and Saul went out to meet him, that he might salute him. 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. And Samuel said to Saul, Thou hast done foolishly; thou hast not kept the commandment of Jehovah thy God, which he commanded thee: for now would Jehovah have established thy kingdom upon Israel for ever. But now thy kingdom shall not continue: Jehovah hath sought him a man after his own heart, and Jehovah hath appointed him to be prince over his people, because thou hast not kept that which Jehovah commanded thee.
