John 9:21 ASV

¹⁹  and asked them, saying, Is this your son, who ye say was born blind? How then doth he now see?

²⁰  His parents answered and said, We know that this is our son, and that he was born blind:

²¹  but 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.

²²  These 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.

²³  Therefore said his parents, He is of age; ask him.
