John Chapter 9, Verse 25
From BibleWiki
25: απεκριθη ουν εκεινος και ειπεν ει αμαρτωλος εστιν ουκ οιδα εν οιδα οτι τυφλος ων αρτι βλεπω
25: He answered and said, Whether he be a sinner or no, I know
not: one thing I know, that, whereas I was blind, now I see.
25: He said therefore to them: If he be a sinner, I know not. One
thing I know, that whereas I was blind now I see.
Whether he be a sinner or no, I know not. The man had just said that he believed Jesus to be a prophet, Jn 9:17. By his saying that he did not know whether he was a sinner may be meant that though he might be a prophet, yet that he might not be perfect; or that it did not become him, being an obscure and unlearned man, to attempt to determine that question. What follows shows that he did not believe that he was a sinner, and these words were probably spoken in irony to deride the Pharisees. They were perverse and full of cavils, and were determined not to believe. The man reminded them that the question was not whether Jesus was a sinner; that, though that might be, yet it did not settle the other question about opening his eyes, which was the chief point of the inquiry.
One thing I know, &c. About this he could have no doubt. He disregarded, therefore, their cavils.
