19. And this is the testimony of John, when the Jews sent from Jerusalem priests and Levites to him, to ask him: Who art thou?
20. And he confessed, and did not deny: and he confessed: I am not the Christ.
21. And they asked him: What then? Art thou Elias? And he said: I am not. Art thou the prophet? And he answered: No.
22. They said therefore unto him: Who art thou, that we may give an answer to them that sent us? What sayest thou of thyself?
23. He said: I am the voice of one crying in the wilderness: Make straight the way of the Lord, as said the prophet Isaias.
