John Chrysostom — as excerpted in the Catena Aurea on John 9:8-17

“(Hom. lvii. 2) The Jews, whom they asked, Where is He? were desirous of finding Him, in order to bring Him to the Pharisees; but, as they could not find Him, they bring the blind man. They brought to the Pharisees him that aforetime was blind; i. e. that they might examine him still more closely. The Evangelist adds, And it was the sabbath day when Jesus made the clay, and opened his eyes; in order to expose their real design, which was to accuse Him of a departure from the law, and thus detract from the miracle: as appears from what follows, Then again the Pharisees also asked him how he had received his sight. But mark the firmness of the blind man. To tell the truth to the multitude before, from whom he was in no danger, was not so great a matter: but it is remarkable, now that the danger is so much greater, to find him disavowing nothing, and not contradicting any thing that he said before: He said unto them, He put clay upon mine eyes, and I washed, and do see. Ho is more brief this time, as his interrogators were already informed of the matter: not mentioning the name of Jesus, nor His saying, Go, and wash; but simply, He put clay upon mine eyes, and I washed, and do see; the very contrary answer to what they wanted. They wanted a disavowal, and they receive a confirmation of the story.”
