John 1:30-34

This is he, &c. I now point out to you the very person of whom I formerly said, After me cometh a man which is preferred before me Being incomparably greater and more excellent than I; for he was That is, he existed; before me Dr. Hammond abundantly vindicates this interpretation. Had πρωτος, rendered before, signified chief here, as in some other places, εστι, is, not ην, was, would have been joined with it, and John would have said he is, and not he was, my chief, which would have been a very flat tautology instead of a reason; whereas Christ's having existed before John, though he was born after him, was a most convincing proof that he was a very extraordinary person, and was the strongest reason that could well have been assigned, to show that he was worthy of their superior regard. And I knew him not When I testified concerning the Messiah that he was soon to appear, and was a much greater person than I was, I did not know that this was he: I only knew in the general, that my mission and baptism were designed by God as the means of making the Messiah known to the Israelites. See the note on Matthew 3:14. The Baptist made this declaration, lest the surrounding multitude should have imagined that Jesus assumed, and that he gave him, the title of Messiah, by private concert between themselves. But how surprising is this that John here asserts, considering how nearly they were related, and how remarkable the conception and birth of them both had been. But through the peculiar providence of God, it was ordered that our Saviour should live from his infancy to his baptism at Nazareth, while John lived all that time the life of a hermit, in the deserts of Judea, ninety or more miles from Nazareth. Hereby that acquaintance was prevented which might have made John's testimony of Christ suspected. And John bare record, saying, I saw the Spirit From the time that the Baptist had the Messiah discovered to him by supernatural revelation, and the appearance of the sign which God had told him of, he openly pointed him out to the Jews, declaring, at the same time, the ground on which he proceeded in this matter, namely, the descent of the Spirit, which was the sign mentioned by God himself.
