John 1:25-27, 31-33

And they asked him, and said unto him, Why then baptizest thou, if thou art not the Christ, neither Elijah, neither the prophet? John answered them, saying, I baptize in water: in the midst of you standeth one whom ye know not, even he that cometh after me, the latchet of whose shoe I am not worthy to unloose.

And I knew him not; but that he should be made manifest to Israel, for this cause came I baptizing in water. And John bare witness, saying, I have beheld the Spirit descending as a dove out of heaven; and it abode upon him. 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.
