Isaiah 42:16-19

16And I will bring the blind by a way that they knew not; I will lead them in paths that they have not known: I will make darkness light before them, and crooked things straight. These things will I do unto them, and not forsake them.1

17They shall be turned back, they shall be greatly ashamed, that trust in graven images, that say to the molten images, Ye are our gods. 18Hear, ye deaf; and look, ye blind, that ye may see. 19Who is blind, but my servant? or deaf, as my messenger that I sent? who is blind as he that is perfect, and blind as the Lord’s servant?
