1 Samuel 13:13-14

Then Samuel said to Saul, “You have behaved foolishly! You have not kept the command of Yahweh your God which he commanded you. For then, Yahweh would have established your kingdom over Israel forever. But now, your kingdom will not endure. Yahweh has sought for himself a man according to his own heart, and Yahweh has appointed him as leader over his people, because you have not kept what Yahweh commanded you.”
