John 1:32-39

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.’ And I have seen and testified that this is the Son of God.” Again, the next day, John stood with two of his disciples. And looking at Jesus as He walked, he said, “Behold the Lamb of God!” The two disciples heard him speak, and they followed Jesus. Then Jesus turned, and seeing them following, said to them, “What do you seek?” They said to Him, “Rabbi” (which is to say, when translated, Teacher), “where are You staying?” He said to them, “Come and see.” They came and saw where He was staying, and remained with Him that day (now it was about the tenth hour).
