1 Samuel 13:13-14

Samuel said to Saul, “You have been foolish.  You have not kept the command the LORD your God gave you.  It was at this time that the LORD would have permanently established your reign over Israel,  but now your reign will not endure.  The LORD has found a man after his own heart,  , and the LORD has appointed him as ruler over his people, because you have not done what the LORD commanded.”
