2 Chronicles 6:15-17

15You have kept what you promised to your servant, my father David. You spoke directly to him, and you fulfilled your promise by your power, as it is today.

16Therefore, Lord God of Israel, keep what you promised to your servant, my father David: “You will never fail to have a man to sit before me on the throne of Israel, if only your sons take care to walk in my Law as you have walked before me.”

17Now, Lord God of Israel, please confirm what you promised to your servant David.
