1 Kings 2:3-4

and observe what the LORD your God requires: Walk in obedience to him, and keep his decrees and commands, his laws and regulations, as written in the Law of Moses. Do this so that you may prosper in all you do and wherever you go and that the LORD may keep his promise to me: ‘If your descendants watch how they live, and if they walk faithfully before me with all their heart and soul, you will never fail to have a successor on the throne of Israel.’
