John Wesley on 2 Samuel 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.
