John 1:23-31

23He said, I am the voice of one crying in the wilderness, Make straight the way of the Lord, as said Isaiah the prophet.

24And they had been sent from the Pharisees.

25And they asked him, and said unto him, Why then baptizest thou, if thou art not the Christ, neither Elijah, neither the prophet?

26John answered them, saying, I baptize with water: in the midst of you standeth one whom ye know not,

27even he that cometh after me, the latchet of whose shoe I am not worthy to unloose.

28These things were done in Bethany beyond Jordan, where John was baptizing.

29On the morrow he 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 become before me: for he was before me.

31And I knew him not; but that he should be made manifest to Israel, for this cause came I baptizing with water.
