They say unto the blind man again, What sayest thou of Him, that He hath opened thine eyes? He said, He is a prophet.
But the Jews did not believe concerning him, that he had been blind, and received his sight, until they called the parents of him that had received his sight.
And they asked them, saying, Is this your son, who ye say was born blind? how then doth he now see?
His parents answered them and said, We know that this is our son, and that he was born blind:
But by what means he now seeth, we know not; or who hath opened his eyes, we know not: he is of age; ask him: he shall speak for himself.
The Pharisees believed they had finally found something for which they could put Jesus on trial, and take His life. Once again, He had performed a miracle (work of healing) on the Sabbath. Moreover, He had claimed to be the Son of God! Such heresy could not be tolerated.
They questioned the blind man again, asking him what he thought about his Healer. The blind man answered, “Well, He must be a prophet!”
The Old Testament scriptures were full of stories of the prophets performing miracles, even bringing someone back to life (I Kings 17:17-24). So it was well within the bounds for the blind man to assume was Jesus was another prophet.
The problem, of course, was that no other prophet had ever claimed to be God incarnate. The Pharisees needed more proof of Jesus’ crimes, so they questioned the blind man again, wanting proof that he had indeed been born blind.
The best witnesses, obviously, were the blind man’s parents. Did you catch the way the Pharisees framed their question? “Is this your son, whom ye say was born blind? How is it, then that he can now see?” Their question was set up to try to catch the parents and their son as liars.
The parents were wary, though. They said, “We know this is our son. We know he was born blind. We do NOT know how he regained his sight. He’s an adult. Ask him. He can speak for himself.”
