John 1:25-27

25 and they asked him, and said to him: Why then dippest thou, if thou not art the Anointed, nor Elias, nor a prophet?

26 Answered then the John, saying: I dip in water; midst but of you stands, whom you not know,

27 he after me coming, of whom I not am worthy, that I may loose of him the strap of the sandal.
