1 Samuel 12:21-25

21And do not turn aside after empty things that cannot profit or deliver, for they are empty.

22For the Lord will not forsake his people, for his great name's sake, because it has pleased the Lord to make you a people for himself.

23Moreover, as for me, far be it from me that I should sin against the Lord by ceasing to pray for you, and I will instruct you in the good and the right way.

24Only fear the Lord and serve him faithfully with all your heart. For consider what great things he has done for you.

25But if you still do wickedly, you shall be swept away, both you and your king."
