1 Samuel 13:11-14

Samuel said, “What have you done?” And Saul said, “When I saw that the people were scattering from me, and that you did not come within the days appointed, and that the Philistines had mustered at Michmash, I said, ‘Now the Philistines will come down against me at Gilgal, and I have not sought the favor of the LORD.’ So I forced myself, and offered the burnt offering.” And Samuel said to Saul, “You have done foolishly. You have not kept the command of the LORD your God, with which he commanded you. For then the LORD would have established your kingdom over Israel forever. But now your kingdom shall not continue. The LORD has sought out a man after his own heart, and the LORD has commanded him to be prince over his people, because you have not kept what the LORD commanded you.”
