25 Now, O Lord, God of Israel, keep the promise you made to your servant, my father David, when you said, ‘You will never fail to have a successor ruling before me on the throne of Israel, provided that your descendants watch their step and serve me as you have done.’

Darby

25 And now, Jehovah, 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 sons take heed to their way, to walk before me as thou hast walked before me.

KJV

25 Therefore now, LORD God of Israel, keep with thy servant David my father that thou promisedst him, saying, There shall not fail thee a man in my sight to sit on the throne of Israel; so that thy children take heed to their way, that they walk before me as thou hast walked before me.
