But by what means he now seeth. — Better, but how he now seeth. The answer is in the exact words of the question, which is not seen in our version. They will not pass beyond the plain matters of fact of which they were certain.
Or who hath opened his eyes. — They pass here to a fourth question, which was not asked, but which they see to be the real point which the Pharisees are aiming at, and in which they have determined not to be entangled.
He is of age, ask him. — The better reading here is probably that which places “ask him” first; ask him, he is of age. The Received text has been influenced by John 9:23. The Greek expresses with the fullest emphasis, which it is not easy to preserve in English, that they intend to have nothing to do with this third question, but to leave it to their son to answer. Literally, it is, Ask him; he is of full age; he himself will speak concerning himself.
