John 9:18-23

18The Jews therefore did not believe concerning him that he was blind and had received sight, until they had called the parents of him that had received sight.

19And they asked them saying, This is your son, of whom ye say that he was born blind: how then does he now see?

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.
