3:4 "Ye are My witnesses, saith the Lord, and My servant whom I have chosen: that ye may know and believe Me, and understand that I am He: before Me there was no God formed, neither shall there be after Me. I, even I, am the Lord; and beside Me there is no Saviour. I have declared, and have saved, and I have showed, when there was no strange god among you: therefore ye are My witnesses." "I the Lord have called thee in righteousness, and will hold thine hand, and will keep thee, and give thee for a covenant of the people, for a light of the Gentiles; to open the blind eyes, to bring out the prisoners from the prison, and them that sit in darkness out of the prison house." Isaiah 43:10-12; 42:6, 7.
