1 Kings 2:3-4

3And keep the charge of the LORD your God to walk in His ways and to keep His statutes, commandments, ordinances, and decrees, as written in the Law of Moses, so that you may prosper in all you do and wherever you turn, 4and so that the LORD may fulfill His promise to me: ‘If your descendants take heed to walk faithfully before Me with all their heart and soul, you will never fail to have a man on the throne of Israel.’
