And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost.

And I knew him not: but he that sent me to baptize in water, he said unto me, Upon whomsoever thou shalt see the Spirit descending, and abiding upon him, the same is he that baptizeth in the Holy Spirit.

And I knew him not; but he who sent me to baptize with water, said to me: He upon whom thou shalt see the Spirit descending, and remaining upon him, he it is that baptizeth with the Holy Ghost.

And I knew him not; but he who sent me to baptise with water, he said to me, Upon whom thou shalt see the Spirit descending and abiding on him, he it is who baptises with the Holy Spirit.

And I knew him not: but he that sent me to baptize with water, the same said to me, Upon whom thou shalt see the Spirit descending and remaining on him, the same is he who baptizeth with the Holy Spirit.

and I did not know him, but he who sent me to baptize with water, He said to me, On whomsoever thou mayest see the Spirit coming down, and remaining on him, this is he who is baptizing with the Holy Spirit;

And I knew him not: but he that sent me to baptize with water, the same said to me, On whom you shall see the Spirit descending, and remaining on him, the same is he which baptizes with the Holy Ghost.

I did not yet know Him, but He who sent me to baptize in water said to me, "'The One on whom you see the Spirit coming down, and remaining, He it is who baptizes in the Holy Spirit.'

I had no knowledge who he was, but he who sent me to give baptism with water said to me, The one on whom you see the Spirit coming down and resting, it is he who gives baptism with the Holy Spirit.

And I did not know him. But he who sent me to baptize with water said to me: 'He over whom you will see the Spirit descending and remaining upon him, this is the one who baptizes with the Holy Spirit.'

I myself did not know him, but he who sent me to baptize with water, he said to me 'He on whom you see the Spirit descending, and remaining on him – he it is who baptizes with the Holy Spirit.'

Upon whom thou shalt see the Spirit descending. Here a difficult question arises; for if John did not know Christ, why does he refuse to admit him to baptism? To a person whom he did not know he would not say, I ought rather to be baptized by thee, (Matthew 3:14.) Some reply, that he knew him to such an extent as to regard him with the reverence due to a distinguished Prophet, but was not aware that he was the Son of God. But this is a poor solution of the difficulty, for every man ought to obey the calling of God without any respect of persons. No rank or excellence of man ought to prevent us from doing our duty, and therefore John would have shown disrespect to God and to his baptism, if he had spoken in this manner to any other person than the Son of God. it follows that he must have previously known Christ. In the first place, it ought to be observed, that the knowledge here mentioned is that which arises from personal and long acquaintance. Although he recognizes Christ whenever he sees him, still it does not cease to be true that they were not known to each other according to the ordinary custom of men, for the commencement of his knowledge proceeded from God. But the question is not yet fully answered; for he says that the sight of the Holy Spirit was the mark by which he was pointed out to him. Now he had not yet seen the Spirit, when he had addressed Christ as the Son of God. For my own part, I willingly embrace the opinion of those who think that this sign was added for confirmation, and that it was not so much for the sake of John as for the sake of us all. John indeed saw it, but it was rather for others than for himself. Bucer appropriately quotes that saying of Moses, This shall be a sign to you, that after three days journey, you shall sacrifice to me on the mountain, (Exodus 3:12.) Undoubtedly, when they were going out, they already knew that God would conduct and watch over their deliverance; but this was a confirmation a posteriori, as the phrase is; that is, from the event, after it had taken place. In like manner, this came as an addition to the former revelation which had been given to John.

The same said - This was the sign by which he was to know the Messiah. He was to see the Spirit descending like a dove and abiding on him. It does not follow, however, that he had no intimation before this that Jesus was the Christ, but it means that by this he should know it infallibly. From Matthew 3:13-14, it seems that John supposed, before the baptism of Jesus, that he claimed to be the Messiah, and, that he believed it; but the infallible, certain testimony in the case was the descent of the Holy Spirit on him at his baptism.
That this is the Son of God - This was distinctly declared by a voice from heaven at his baptism, Matthew 3:17. This John heard, and he testified that he had heard it.

He that sent me - said unto me - From this we may clearly perceive that John had a most intimate acquaintance with the Divine Being; and received not only his call and mission at first, but every subsequent direction, by immediate, unequivocal inspiration. Who is fit to proclaim Jesus, but he who has continual intercourse with God; who is constantly receiving light and life from Christ their fountain; who bears a steady, uniform testimony to Jesus, even in the presence of his enemies; and who at all times abases himself, that Jesus alone may be magnified! Reformation of manners, and salvation of souls, will accompany such a person's labors whithersoever he goeth.

And I knew him not,.... That is, before he came to be baptized by him; when it was secretly suggested to him who he was, and the following signal was given him, to confirm him in it:
but he that sent me to baptize with water; or "in water"; that is, God; for John's mission was from God, as in John 1:6, and his baptism from heaven; he had a divine warrant and commission for what he did:
the same said unto me; either by an articulate voice, or by a divine impulse on his mind, or by the revelation of the Spirit:
upon whom thou shalt see the Spirit descending and remaining on him, the same is he which baptizeth with the Holy Ghost; that is, the Messiah; See Gill on Matthew 3:11, Matthew 3:16.
