John 9:20

18The Jews therefore didn’t believe concerning him, that he had been blind and had received his sight, until they called the parents of him who had received his sight,

19and asked them, “Is this your son, whom you say was born blind? How then does he now see?”

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

21but how 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; for the Jews had already agreed that if any man would confess him as Christ, he would be put out of the synagogue.
