Let the Reader observe in the close, as in the opening of the Psalm, that the sacred writer speaks of one identical person. It is the righteous one Jehovah will bless: it is him that is to be compassed as with a shield. And who is this righteous person, but the Lord Jesus, the glorious righteous Mediator? In whom are the people to put their trust, and in whom are they to shout for joy, but in Jesus, who is their salvation? Yes! Lord, thou art righteous, and the Lord our righteousness! Everlasting praises to him, who, though he knew no sin, was made sin for us, that we might be made the righteousness of God in him. 2 Corinthians 5:21.
