Matthew Henry on 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. (1Ki 2:5-11)
