12 When your days are fulfilled and you lie down with your ancestors, I will raise up your offspring after you, who shall come forth from your body, and I will establish his kingdom. 13 He shall build a house for my name, and I will establish the throne of his kingdom forever. 14 I will be a father to him, and he shall be a son to me. When he commits iniquity, I will punish him with a rod such as mortals use, with blows inflicted by human beings. 15 But I will not take my steadfast love from him, as I took it from Saul, whom I put away from before you. 16 Your house and your kingdom shall be made sure forever before me; your throne shall be established forever. 17 In accordance with all these words and with all this vision, Nathan spoke to David.
Matthew Henry's Commentary on 2 Samuel 7:12-17
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.
