John 1:25-27

25 And they asked him and said to him, Why baptizest thou then, if thou art not the Christ, nor Elijah, neither that prophet?

26 John answered them, saying, I baptize with water, but there standeth one among you whom ye know not.

27 He it is, who coming after me, is preferred before me, whose shoes latchet I am not worthy to unloose.
