John 1:29-31

New Revised Standard Version, Anglicised Catholic Edition

The Lamb of God

²⁹ The next day he saw Jesus coming towards him and declared, ‘Here is 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 ahead of me because he was before me.” ³¹ I myself did not know him; but I came baptizing with water for this reason, that he might be revealed to Israel.’
