This large description of God's infinite power is here seasonably added, to give assurance of the certain accomplishment of these great and wonderful promises, which otherwise would seem incredible. I the Lord have called thee in righteousness To declare my righteousness, as is said Romans 3:26: or, my faithfulness, manifested in fulfilling my promises, long since made, and often renewed; and will hold thy hand Will give thee counsel and strength for thy great and mighty work. And will keep thee That thou shalt not fail in, nor, by thine enemies, be hindered from, the accomplishment of thy work; and give thee for a covenant of the people To be the Angel of the covenant, Malachi 3:1; or, the Mediator, in and by whom my covenant of grace is made and confirmed with mankind, even with all people who will accept of it. For a light of the Gentiles To enlighten them with true and saving knowledge, and to direct them in the right way to true happiness, out of which they had miserably wandered. To open the blind eyes The eyes of men's minds, blinded with long ignorance, deep prejudice, and inveterate error, and by the god of this world, 2 Corinthians 4:4. And to bring out the prisoners, &c. Namely, sinners who are taken captive by the devil at his will, (2 Timothy 2:26,) and enslaved by their own lusts, and who can only be made free by Christ, John 8:32; John 8:36: compare Isaiah 61:1, and Luke 4:17-21.
