To open the blind eyes, to bring out the prisoners from the prison, and them that sit in darkness out of the prison house.
To open the blind eyes - spiritually (Isaiah 42:16; Isaiah 42:18-19; Isaiah 35:5; John 9:39).
To bring out the prisoners from the prison - (Isaiah 61:1-2.)
And them that sit in darkness - opposed to "light" (Isaiah 42:6; Ephesians 5:8; 1 Peter 2:9).
