John 9:28 Meaning

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

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

28Then they reviled him, and said, Thou art his disciple; but we are Moses' disciples.

29We know that God spake unto Moses: as for this fellow, we know not from whence he is.

30The man answered and said unto them, Why herein is a marvellous thing, that ye know not from whence he is, and yet he hath opened mine eyes.
