Isaiah 42:6-7

I the Lord have called You [the Messiah] for a righteous purpose and in righteousness; I will take You by the hand and will keep You; I will give You for a covenant to the people [Israel], for a light to the nations [Gentiles], To open the eyes of the blind, to bring out prisoners from the dungeon, and those who sit in darkness from the prison. [Matt. 12:18-21.]
