16 `And now, O Jehovah, God of Israel, keep for Thy servant David my father that which Thou didst speak to him, saying, There is not cut off to thee a man from before Me, sitting on the throne of Israel, only, if thy sons watch their way to walk in My law, as thou hast walked before Me.
16
“Now, LORD, the God of Israel, keep for your servant David my father the promises you made to him when you said, ‘You shall never fail to have a successor to sit before me on the throne of Israel, if only your descendants are careful in all they do to walk before me according to my law, as you have done.’
