John 9:18

15 Again, therefore, the Pharisees also were asking him how he received sight, and he said to them, `Clay he did put upon my eyes, and I did wash -- and I see.`

16 Of the Pharisees, therefore, certain said, `This man is not from God, because the sabbath he doth not keep;` others said, `How is a man -- a sinful one -- able to do such signs?` and there was a division among them.

17 They said to the blind man again, `Thou -- what dost thou say of him -- that he opened thine eyes?`

18 and he said -- `He is a prophet.` The Jews, therefore, did not believe concerning him that he was blind and did receive sight, till that they called the parents of him who received sight,

19 and they asked them, saying, `Is your son, of whom ye say that he was born blind? how then now doth he see?`

20 His parents answered them and said, `We have known that this is our son, and that he was born blind;

21 and how he now seeth, we have not known; or who opened his eyes, we have not known; himself is of age, ask him; he himself shall speak concerning himself.`
