21 As the time of King David's death approached, he gave this charge to his son Solomon: 2 "I am going where everyone on earth must someday go. Take courage and be a man. 3 Observe the requirements of the Lord your God, and follow all his ways. Keep the decrees, commands, regulations, and laws written in the Law of Moses so that you will be successful in all you do and wherever you go. 4 If you do this, then the Lord will keep the promise he made to me. He told me, 'If your descendants live as they should and follow me faithfully with all their heart and soul, one of them will always sit on the throne of Israel.'

David's charge to Solomon is, to keep the charge of the Lord. The authority of a dying father is much, but nothing to that of a living God. God promised David that the Messiah should come from his descendants, and that promise was absolute; but the promise, that there should not fail of them a man on the throne of Israel, was conditional; if he walks before God in sincerity, with zeal and resolution: in order hereunto, he must take heed to his way.
