7:14 I will be his father, and he shall be my son. If he commit iniquity, I will chasten him with the {f} rod of men, and with the stripes of the children of men:
(f) That is, gently, as fathers use to chastise their children.
7:14 His father - I will carry myself towards him as a father, with all affection, and I will own him as my son. This is intended both of Solomon, as a type of Christ; and of Christ himself as is evident from Heb 1:5. If he commit - This agrees only to Solomon and some others of David's posterity; but not to Christ, who never committed iniquity, as Solomon did, who therein was no type of Christ, and therefore this branch is terminated in Solomon; whereas in those things wherein Solomon was a type of Christ, the sense passes through Solomon to Christ. Rod of men - With such rods as are gentle and moderate, and suited to man's weakness.
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.
