John 9:18-20

Amplified Bible, Classic Edition

¹⁸ However, the Jews did not believe that he had [really] been blind and that he had received his sight until they called (summoned) the parents of the man.

¹⁹ They asked them, Is this your son, whom you reported as having been born blind? How then does he see now?

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