'Descendants' in the Bible

and the Lord will fulfill his promise to me, 'If your descendants watch their step and live faithfully in my presence with all their heart and being, then,' he promised, 'you will not fail to have a successor on the throne of Israel.'

May Joab and his descendants be perpetually guilty of their shed blood, but may the Lord give perpetual peace to David, his descendants, his family, and his dynasty."

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.'

Their descendants remained in the land (the Israelites were unable to wipe them out completely). Solomon conscripted them for his work crews, and they continue in that role to this very day.

I will humiliate David's descendants because of this, but not forever."
