John 9:17 - Clarke's commentary and critical notes on the Bible

They say unto the blind man again, What sayest thou of him, that he hath opened thine eyes? He said, He is a prophet. He is a prophet - They had intended to lay snares for the poor man, that, getting him to acknowledge Christ for the Messiah, they might put him out of the synagogue, John 9:22, or put him to death, that such a witness to the Divine power of Christ might not appear against them. But, as the mercy of God had given him his sight, so the wisdom of God taught him how to escape the snares laid for his ruin. On all thy glory there shall be a defense, says the prophet, Isaiah 4:5. When God gives any particular mercy or grace, he sends power to preserve it, and wisdom to improve it. The man said, He is a prophet. Now, according to a Jewish maxim, a prophet might dispense with the observation of the Sabbath. See Grotius. If they allow that Jesus was a prophet, then, even in their sense, he might break the law of the Sabbath, and be guiltless: or, if they did not allow him to be a prophet, they must account for the miracle some other way than by the power of God; as from Satan or his agents no good can proceed - to do this it was impossible. So the wisdom of God taught the poor man to give them such an answer as put them into a complete dilemma, from which they could not possibly extricate themselves.
