John 9:20-27

20His parents answered [them] and said, We know that this is our son, and that he was born blind;

21but how he now sees we do not know, or who has opened his eyes we do not know. He is of age: ask him; he will speak concerning himself.

22His parents said these things because they feared the Jews, for the Jews had already agreed that if any one confessed him [to be the] Christ, he should be excommunicated from the synagogue.

23On this account his parents said, He is of age: ask him.

24They called therefore a second time the man who had been blind, and said to him, Give glory to 1God: we know that this man is sinful.

25He answered therefore, If he is sinful I know not. One thing I know, that, being blind [before], now I see.

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

27He answered them, I told you already and ye did not hear: why do ye desire to hear again? do ye also wish to become his disciples?
