John 9
18 Ref Now the Jews had no belief in the statement that he had been blind and was now able to see, till they sent for the father and mother of the man whose eyes had been made open,
19 Ref And put the question to them, saying, Is this your son, of whom you say that he was blind at birth? how is it then that he is now able to see?
20 In answer his father and mother said, We are certain that this is our son and that he was blind at birth:
21 But how it is he is now able to see, or who made his eyes open, we are not able to say: put the question to him; he is old enough to give an answer for himself.
