1 Kings 2:3-4

and keep the charge of the LORD your God, walking in his ways and keeping his statutes, his commandments, his rules, and his testimonies, as it is written in the Law of Moses, that you may prosper in all that you do and wherever you turn, that the LORD may establish his word that he spoke concerning me, saying, ‘If your sons pay close attention to their way, to walk before me in faithfulness with all their heart and with all their soul, you shall not lack a man on the throne of Israel.’
