John 9:25

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

²⁴  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.

²⁵  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.

²⁶  Then said they to him again, What did he to thee? how opened he thine eyes?

²⁷  He answered them, I have told you already, and ye did not hear: wherefore would ye hear it again? will ye also be his disciples?
