1 Samuel 13:8-14

¶ And he tarried seven days, according to the set time that Samuel had appointed, but Samuel did not come to Gilgal, and the people were deserting from him. Then Saul said, Bring me a burnt offering and peace offerings. And he offered the burnt offering. And it came to pass that as soon as he had finished offering the burnt offering, behold, Samuel came; and Saul went out to meet him that he might bless him. Then Samuel said, What hast thou done? And Saul said, Because I saw that the people were leaving me and that thou didst not come within the days appointed and that the Philistines gathered themselves together at Michmash, therefore, I said, The Philistines will come down now upon me to Gilgal, and I have not made supplication unto the LORD. I forced myself, therefore, and offered a burnt offering. Then Samuel said to Saul, Thou hast done foolishly; thou hast not kept the commandment of the LORD thy God, which he commanded thee, for now the thy God, which he commanded thee, for now the LORD would have established thy kingdom over Israel for ever. But now thy kingdom shall not stand; the LORD has sought a man after his own heart unto whom the has sought a man after his own heart unto whom the LORD has commanded that he be captain over his people because thou hast not kept that which the LORD commanded thee.
