John 1:29-31

²⁹ The next day he saw Jesus coming toward him, and said, “Behold, the Lamb of God, who takes away the sin of the world! ³⁰ This is he of whom I said, ‘After me comes a man who ranks before me, because he was before me.’ ³¹ I myself did not know him, but for this purpose I came baptizing with water, that he might be revealed to Israel.”
