John 9:20-27

²⁰So his parents answered them and said: “We know that this is our son, and that he was born blind;

²¹but by what means he now sees we don't know, or who opened his eyes we don't know. He is of age. Ask him. He will speak for himself.”

²²His parents said these things because they feared the Jews, because the Jews had already agreed that if anyone confessed Him to be Christ he would be barred from the synagogue.

²³That is why his parents said, “He is of age; ask him.”

²⁴So they summoned the man who had been blind a second time and said to him: “Give glory to God! We know that this man is a sinner.”

²⁵So he answered and said: “That He is a sinner, I do not know. One thing I do know, that having been blind I now see!”

²⁶So they said to him again: “What did he do to you? How did he open your eyes?”

²⁷He answered them: “I already told you and you didn't listen. Why do you want to hear it again? You don't want to become His disciples too, do you?”
