John 9:19 (KJV)

And it was the sabbath day when Jesus made the clay, and opened his eyes.

Then again the Pharisees also asked him how he had received his sight. He said unto them, He put clay upon mine eyes, and I washed, and do see.

Therefore said some of the Pharisees, This man is not of God, because he keepeth not the sabbath day. Others said, How can a man that is a sinner do such miracles? And there was a division among them.

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

But 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.

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

But 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.

These 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.

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

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