(19) Is this your son, who ye say was born blind?—The “ye” is emphatic; ye say he was born blind, as opposed to us, for we do not believe it. There are three questions. Is this your son? Do ye still say that he was born blind? which is incredible, as he now possesses the faculty of sight (John 9:32). If you do, how do you account for the fact that he now sees?

How then doth he now see?—Their question means—“How does it come to pass, since he was born blind, that he all at once seeth?” The word rendered “now,” here and in John 9:21; John 9:25, conveys the idea of the suddenness of the change which had taken place.

9:18-23 The Pharisees vainly hoped to disprove this notable miracle. They expected a Messiah, but could not bear to think that this Jesus should be he, because his precepts were all contrary to their traditions, and because they expected a Messiah in outward pomp and splendour. The fear of man brings a snare, Pr 29:25, and often makes people deny and disown Christ and his truths and ways, and act against their consciences. The unlearned and poor, who are simple-hearted, readily draw proper inferences from the evidences of the light of the gospel; but those whose desires are another way, though ever learning, never come to the knowledge of the truth.Is this your son? ... - The Pharisees proposed three questions to the parents, by which they hoped to convict the man of falsehood:

1. Whether he was their son?

2. Whether they would affirm that he was born blind? and,

3. Whether they knew by what means he now saw?

They evidently intended to intimidate the parents, so that they might give an answer to one of these questions that would convict the man of deception. We see here the art to which men will resort rather than admit the truth. Had they been half as much disposed to believe on Jesus as they were to disbelieve, there would have been no difficulty in the case. And so with all men: were they as much inclined to embrace the truth as they are to reject it, there would soon be an end of cavils.

18-23. the Jews did not believe … he had been born blind … till they called the parents of him that had received his sight—Foiled by the testimony of the young man himself, they hope to throw doubt on the fact by close questioning his parents, who, perceiving the snare laid for them, ingeniously escape it by testifying simply to the identity of their son, and his birth-blindness, leaving it to himself, as a competent witness, to speak as to the cure. They prevaricated, however, in saying they "knew not who had opened his eyes," for "they feared the Jews," who had come to an understanding (probably after what is recorded, Joh 7:50, &c.; but by this time well known), that whoever owned Him as the Christ would be put out of the synagogue—that is, not simply excluded, but excommunicated. The parents of this man that was blind, in their answer show a great deal of discretion and prudence. Three things the Pharisees ask:

1. Whether this was their son?

2. Whether (as they said) he was indeed born blind?

3. How he came now to see?

The manner of the propounding their question,

who ye say, lets us know what answer they would have had, and that they did not send for the parents of this blind man out of a desire to know the naked truth of the thing, but hoping to fright them into a speaking doubtfully (at least) whether it was their son, yea or no; or whether he was stark blind when he was born, yea or no. But, alas! The providence of God ordering his condition to be so poor, that he was glad to beg for his livelihood, made this design vain, would his parents have gratified the Pharisees by any shuffling and indirect answer.

And they asked them, saying, is this your son,.... The first question they put was, whether the man that stood before them, pointing to him, was their son or not; whether they knew him by any marks to be their son, and would own him as such: had they answered to this in the negative, they would have got an advantage against him, and would have convicted him of a lie, since he had given out that he was the son of such parents; and proving such a lie upon him, would at once have brought the whole affair into suspicion at least: they add,

who ye say was born blind; this contains a second question, whether, if this was their son, he was born blind or not; and if he was not born blind, though he had been blind, it would have greatly lessened the miracle: and besides, they would have put other questions upon this, whether his blindness was real, and by what means it came. Next follows a third question,

how then doth he now see? By what means has he received his sight? They might hope, that if he was their son, and was really born blind, that he had his sight some other way than by Jesus; or they might object this to his being born, blind, as being a thing impossible, or at least not credible that he should ever see, was that the case.

And they asked them, saying, Is this your son, who ye say was born blind? how then doth he now see?
