2 Chronicles 6:15-17

15You have kept the promise You made to Your servant David, my father. Surely you spoke with Your mouth and have fulfilled it with Your hand—as it is today.

16“Now therefore, Adonai, God of Israel, keep for Your servant David, my father, that which You have promised him saying: ‘For you will never be cut off, you will not fail to have a man sit before Me on the throne—if only your sons pay attention to their way, to walk in My Torah as you have walked before Me.’

17“Now therefore, Adonai God of Israel, let Your word, which You spoke to Your servant David, be confirmed.
