John 1:25-30

And they asked him, and said unto him, Why then baptizest thou, if thou art not the Christ, neither Elijah, neither the prophet? John answered them, saying, I baptize in water: in the midst of you standeth one whom ye know not, even he that cometh after me, the latchet of whose shoe I am not worthy to unloose. These things were done in Bethany beyond the Jordan, where John was baptizing. On the morrow he seeth Jesus coming unto him, and saith, Behold, the Lamb of God, that taketh away the sin of the world! This is he of whom I said, After me cometh a man who is become before me: for he was before me.
