John 9:18-23

18The Jews therefore did not believe concerning him, that he had been blind, and had received his sight, until they called the parents of him that had received his sight, 19and asked them, saying, Is this your son, who ye say was born blind? how then doth he now see? 20His parents answered and said, We know that this is our son, and that he was born blind: 21but how he now seeth, we know not; or who opened his eyes, we know not: ask him; he is of age; he shall speak for himself. 22These things said his parents, because they feared the Jews: for the Jews had agreed already, that if any man should confess him to be Christ, he should be put out of the synagogue. 23Therefore said his parents, He is of age; ask him.
