John 1:33

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 .
