2 “I am going the way of all the earth. You be strong therefore, and show yourself a man; 3 and keep the instruction of Yahweh your God, to walk in his ways, to keep his statutes, his commandments, his ordinances, and his testimonies, according to that which is written in the law of Moses, that you may prosper in all that you do, and wherever you turn yourself. 4 That Yahweh may establish his word which he spoke concerning me, saying, ‘If your children take heed to their way, to walk before me in truth with all their heart and with all their soul, there shall not fail you,’ he said, ‘a man on the throne of Israel.’
Matthew Henry's Commentary on 1 Kings 2:2-4
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.
