John 1:25-27, 31-33

And they asked him, saying, “Why then do you baptize if you are not the Christ, nor Elijah, nor the Prophet?” John answered them, saying, “I baptize with water, but there stands One among you whom you do not know. It is He who, coming after me, is preferred before me, whose sandal strap I am not worthy to loose.”

I did not know Him; but that He should be revealed to Israel, therefore I came baptizing with water.” And John bore witness, saying, “I saw the Spirit descending from heaven like a dove, and He remained upon Him. I did not know Him, but He who sent me to baptize with water said to me, ‘Upon whom you see the Spirit descending, and remaining on Him, this is He who baptizes with the Holy Spirit.’
