John 1:31-33

Even I did not know who he was, although I came baptizing with water so that the people of Israel would know who he is.” Then John said, “I saw the Spirit come down from heaven in the form of a dove and rest on him. Until then I did not know who the Christ was. But the God who sent me to baptize with water told me, ‘You will see the Spirit come down and rest on a man; he is the One who will baptize with the Holy Spirit.’
