For thou, Lord, wilt bless the righteous. As he has blessed him with a righteousness, even the righteousness of God imputed to him, by which he is denominated righteous, and with the forgiveness of his sins; so he will bless him with peace and prosperity, with all spiritual blessings, with the blessings of grace here, and glory hereafter.
Hence he has just reason to rejoice and be glad;with favour wilt thou compass him as [with] a shield: by which is meant the free favour, love, and grace of God in Christ, which springs from his sovereign will and pleasure; is his good will to men, and the exceeding riches of his grace, shown in his kindness towards them in Christ Jesus: and the compassing or crowning of the righteous with it, as the word signifies, is expressive of the abundance of it, in the application of it to them in conversion, and in every instance and blessing of grace; for such are crowned with lovingkindness and tender mercies; the grace of the Lord is exceeding abundant towards them, it flows and overflows; it surrounds them on all sides, and covers them all over: it is as a shield unto them from all their enemies, Ps 40:11; and which being held in the hand of faith, quenches the fiery darts of Satan; and is the saints security from every enemy, and from all hurt and danger, here or hereafter; see Zep 3:17; and is a crown of glory upon them, which makes them glorious, lovely, and amiable.
