John 9:17-21

So they *said again to the man who was blind, “What do you say about Him, since He opened your eyes?” And he said, “He is a prophet.”

The Jews then did not believe it about him, that he had been blind and had received sight, until they called the parents of the very one who had received his sight,

and they questioned them, saying, “Is this your son, who you say was born blind? Then how does he now see?”

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

but how he now sees, we do not know; or who opened his eyes, we do not know. Ask him; he is of age, he will speak for himself.”
