Therefore now, O LORD, God of Israel, keep for Your servant, my father David, what You promised when You said: ‘You will never fail to have a man to sit before Me on the throne of Israel, if only your descendants guard their way to walk in My law as you have walked before Me.’
Jewish Publication Society of America Version (JPS1917) - 2 Chronicles 6:16 >Now therefore, O LORD, 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.
