John 9:1-4 King James Version (KJV)
9 And as Jesus passed by, he saw a man which was blind from his birth.
2 And his disciples asked him, saying, Master, who did sin, this man, or his parents, that he was born blind?
3 Jesus answered, Neither hath this man sinned, nor his parents: but that the works of God should be made manifest in him.
4 I must work the works of him that sent me, while it is day: the night cometh, when no man can work.
