John 9:22-26

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.

He 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.

Then said they to him again, What did he to thee? how opened he thine eyes?
