John 1:27-31
27He it is, who coming after me is preferred before me, whose shoe's latchet I am not worthy to unloose.
28These things were done in Bethabara beyond Jordan, where John was baptizing.
29The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
30This is he of whom I said, After me cometh a man which is preferred before me: for he was before me.
31And I knew him not: but that he should be made manifest to Israel, therefore am I come baptizing with water.
(KJV)
