1 Samuel 13:13-14

13:13 Then Samuel said to Saul, “You have made a foolish choice! You have not obeyed the commandment that the Lord your God gave you. Had you done that, the Lord would have established your kingdom over Israel forever! 13:14 But now your kingdom will not continue! The Lord has sought out for himself a man who is loyal to him and the Lord has appointed him to be leader over his people, for you have not obeyed what the Lord commanded you.”
