John 9:19 ASV

¹⁷  They say therefore unto the blind man again, What sayest thou of him, in that he opened thine eyes? And he said, He is a prophet.

¹⁸  The 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,

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.
