John 1:29-31

Young's Literal Translation

²⁹ on the morrow John seeth Jesus coming unto him, and saith, `Lo, the Lamb of God, who is taking away the sin of the world;

³⁰ this is he concerning whom I said, After me doth come a man, who hath come before me, because he was before me:

³¹ and I knew him not, but, that he might be manifested to Israel, because of this I came with the water baptizing.
