John 9:21

18 They still did not believe that he had been blind and had received his sight until they sent for the man’s parents. 19 “Is this your son?” they asked. “Is this the one you say was born blind? How is it that now he can see?”

20 “We know he is our son,” the parents answered, “and we know he was born blind. 21 But how he can see now, or who opened his eyes, we don’t know. Ask him. He is of age; he will speak for himself.” 22 His parents said this because they were afraid of the Jewish leaders, who already had decided that anyone who acknowledged that Jesus was the Messiah would be put out of the synagogue. 23 That was why his parents said, “He is of age; ask him.”

24 A second time they summoned the man who had been blind. “Give glory to God by telling the truth,” they said. “We know this man is a sinner.”
