John 9:20-27

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 his parents spoke, because they feared the Jews: for the Jews had agreed already, that if any man confessed that he was Christ, he should be put out of the synagogue. 23Therefore said his parents, He is of age; ask him. 24Then again they called the man that was blind, and said to him, Give God the praise: we know that this man is a sinner. 25He answered and said, Whether he is a sinner, I know not: one thing I know, that, though I was blind, now I see. 26Then they said to him again, What did he to thee? how opened he thy eyes? 27He answered them, I have told you already, and ye did not hear: Why would ye hear it again? will ye also be his disciples?
