John 1:25-27

25 And they asked him, and said to him, What then baptizest thou, if thou art not Christ, neither Elijah, neither a prophet?

26 John answered to them, and said, I baptize in water, but in the middle of you hath stand [or stood] one, that ye know not;

27 he it is, that shall come after me, that was made before me, of whom I am not worthy to loosen the thong of his shoe.
