1 Samuel 13:13-14

Samuel said to Saul, “You have done foolishly. You have not kept the commandment of the LORD your God, which he commanded you; for now the LORD would have established your kingdom on Israel forever. But now your kingdom will not continue. The LORD has sought for himself a man after his own heart, and the LORD has appointed him to be prince over his people, because you have not kept that which the LORD commanded you.”
