12 And when the time comes for you to go to rest with your fathers, I will put in your place your seed after you, the offspring of your body, and I will make his kingdom strong. 13 He will be the builder of a house for my name, and I will make the seat of his authority certain for ever. 14 I will be to him a father and he will be to me a son: if he does wrong, I will give him punishment with the rod of men and with the blows of the children of men; 15 But my mercy will not be taken away from him, as I took it from him who was before you. 16 And your family and your kingdom will keep their place before me for ever: the seat of your authority will never be overturned.
Matthew Henry's Commentary on 2 Samuel 7:12-16
Commentary on 2 Samuel 7:4-17
(Read 2 Samuel 7:4-17)
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.
