John 1:29-31

The next day John saw Jesus coming toward him and said, “Look! The Lamb of God who takes away the sin of the world! He is the one I was talking about when I said, ‘A man is coming after me who is far greater than I am, for he existed long before me.’ I did not recognize him as the Messiah, but I have been baptizing with water so that he might be revealed to Israel.”
