John 1:29-31 NIV

[29] The next day John saw Jesus coming toward him and said, “Look, the Lamb of God, who takes away the sin of the world! [30] This is the one I meant when I said, ‘A man who comes after me has surpassed me because he was before me.’ [31] I myself did not know him, but the reason I came baptizing with water was that he might be revealed to Israel.”
