4 Then the Lord will establish his word that he spoke concerning me: "If your heirs take heed to their way, to walk before me in faithfulness with all their heart and with all their soul, there shall not fail you a successor on the throne of Israel.'
Matthew Henry's Commentary on 1 Kings 2:4
Commentary on 1 Kings 2:1-4
(Read 1 Kings 2:1-4)
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.
