David's care for the ark. (1-3) God's covenant with David. (4-17) His prayer and thanksgiving. (18-29)
Verses 1-3 David being at rest in his palace, considered how he might best employ his leisure and prosperity in the service of God. He formed a design to build a temple for the ark. Nathan here did not speak as a prophet, but as a godly man, encouraging David by his private judgment. We ought to do all we can to encourage and promote the good purposes and designs of others, and, as we have opportunity, to forward a good work.
Verses 4-17 Blessings are promised to the family and posterity of David. These promises relate to Solomon, David's immediate successor, and the royal line of Judah. But they also relate to Christ, who is often called David and the Son of David. To him God gave all power in heaven and earth, with authority to execute judgment. He was to build the gospel temple, a house for God's name; the spiritual temple of true believers, to be a habitation of God through the Spirit. The establishing of his house, his throne, and his kingdom for ever, can be applied to no other than to Christ and his kingdom: David's house and kingdom long since came to an end. The committing iniquity cannot be applied to the Messiah himself, but to his spiritual seed; true believers have infirmities, for which they must expect to be corrected, though they are not cast off.
Verses 18-29 David's prayer is full of the breathings of devout affection toward God. He had low thoughts of his own merits. All we have, must be looked upon as Divine gifts. He speaks very highly and honourably of the Lord's favours to him. Considering what the character and condition of man is, we may be amazed that God should deal with him as he does. The promise of Christ includes all; if the Lord God be ours, what more can we ask, or think of? ( Ephesians 3:20 ) . He knows us better than we know ourselves; therefore let us be satisfied with what he has done for us. What can we say more for ourselves in our prayers, than God has said for us in his promises? David ascribes all to the free grace of God. Both the great things He had done for him, and the great things He had made known to him. All was for his word's sake, that is, for the sake of Christ the eternal Word. Many, when they go to pray, have their hearts to seek, but David's heart was found, that is, it was fixed; gathered in from its wanderings, entirely engaged to the duty, and employed in it. That prayer which is from the tongue only, will not please God; it must be found in the heart; that must be lifted up and poured out before God. He builds his faith, and hopes to speed, upon the sureness of God's promise. David prays for the performance of the promise. With God, saying and doing are not two things, as they often are with men; God will do as he hath said. The promises of God are not made to us by name, as to David, but they belong to all who believe in Jesus Christ, and plead them in his name.
This chapter expresses David's concern for building an house for the ark of God, which he communicated to Nathan the prophet, and was approved of by him, 2Sa 7:1-3; and who was that night sent by the Lord to David, to acquaint him, that as he had for many years dwelt in a tent, and had never given directions to the tribes of Israel, and the rulers of them, to build him an house, so neither should David build him one; but his son that would succeed him in the throne should; and also observes to him the many great things he had done for him, and promises him more, and particularly the establishment of his throne and kingdom for ever, in which he has respect to the Messiah, that should spring from him, 2Sa 7:4-17. Then follows a prayer of David, in which he expresses the sense he had of the greatness and goodness of God, and of his own unworthiness to receive such favours from him he had, returns him thanks for the promises he had made, and prays for the performance of them, 2Sa 7:18-29.
