2 Chronicles 6:15-17

15who hast kept with thy servant David my father that which thou didst promise him: yea, thou spakest with thy mouth, and hast fulfilled it with thy hand, as it is this day. 16Now therefore, O Jehovah, the God 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 children take heed to their way, to walk in my law as thou hast walked before me. 17Now therefore, O Jehovah, the God of Israel, let thy word be verified, which thou spakest unto thy servant David.
