John 1:29-31

The next day John saw Jesus coming toward him. John said, “Look, the Lamb of God, who takes away the sin of the world! This is the One I was talking about when I said, ‘A man will come after me, but he is greater than I am, because he was living before me.’ 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.”
