John 1:32-36

And John testified, “I saw the Spirit descending from heaven like a dove, and he rested on him. I didn’t know him, but he who sent me to baptize with water told me, ‘The one you see the Spirit descending and resting on — he is the one who baptizes with the Holy Spirit.’ I have seen and testified that this is the Son of God.” The next day, John was standing with two of his disciples. When he saw Jesus passing by, he said, “Look, the Lamb of God!”
