2 Chronicles 6:15-17

15who hast kept with thy servant David my father that which thou didst promise him; thou spokest with thy mouth, and hast fulfilled [it] with thy hand as at this day.

16And now, Jehovah, 1God of Israel, keep with thy servant David my father that which thou hast promised him saying, There shall not fail thee a man in my sight to sit on the throne of Israel, if only thy sons take heed to their way to walk in my law, as thou hast walked before me.

17And now, Jehovah, 2God of Israel, let thy word be verified which thou hast spoken unto thy servant David.
