Isaiah Chapter 42:6-7
I the Lord have called you in righteousness, and will hold your hand, and will keep you, and give you for a covenant of the people, for a light to the nations; to open the blind eyes, to bring out the prisoners from the prison, and those who sit in darkness, out of the prison house.
