John 9:21

17They say unto the blind man again, What sayest thou of him, that he hath opened thine eyes? He said, He is a prophet.

18But the Jews did not believe concerning him, that he had been blind, and received his sight, until they called the parents of him that had received his sight.

19And they asked them, saying, Is this your son, who ye say was born blind? how then doth he now see?

20His parents answered them and said, We know that this is our son, and that he was born blind:

21But by what means he now seeth, we know not; or who hath opened his eyes, we know not: he is of age; ask him: he shall speak for himself.

22These words spake his parents, because they feared the Jews: for the Jews had agreed already, that if any man did confess that he was Christ, he should be put out of the synagogue.

23Therefore said his parents, He is of age; ask him.

24Then again called they the man that was blind, and said unto him, Give God the praise: we know that this man is a sinner.

25He answered and said, Whether he be a sinner or no, I know not: one thing I know, that, whereas I was blind, now I see.
