John 9:18

Again therefore the Pharisees also asked him how he received his sight. He said to them, “He put mud on my eyes, I washed, and I see.”

Some therefore of the Pharisees said, “This man is not from God, because he doesn’t keep the Sabbath.”

Others said, “How can a man who is a sinner do such signs?” So there was division among them.

Therefore they asked the blind man again, “What do you say about him, because he opened your eyes?”

He said, “He is a prophet.”

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

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

but 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.”
