1 Samuel 13:13-14

13And Samuel said to Saul, a“You have done foolishly. bYou 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. 14But now cyour kingdom shall not continue. The Lord has sought out a man dafter his own heart, and the Lord has commanded him to be prince
Or leader
over his people, because you have not kept what the Lord commanded you.”
