John 1:24

21 And they questioned him, `What then? Elijah art thou?` and he saith, `I am not.` -- `The prophet art thou?` and he answered, `No.`

22 They said then to him, `Who art thou, that we may give an answer to those sending us? what dost thou say concerning thyself?`

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

25 and they questioned him and said to him, `Why, then, dost thou baptize, if thou art not the Christ, nor Elijah, nor the prophet?`

26 John answered them, saying, `I baptize with water, but in midst of you he hath stood whom ye have not known, this one it is who is coming after me, who hath been before me,

27 of whom I am not worthy that I may loose the cord of his sandal.`
