19And this is the witness of John, when the Jews sent unto him from Jerusalem priests and Levites to ask him, Who art thou? 20And he confessed, and denied not; and he confessed, I am not the Christ. 21And they asked him, What then? Art thou Elijah? And he saith, I am not. Art thou the prophet? And he answered, No. 22They said therefore unto him, Who art thou? that we may give an answer to them that sent us. What sayest thou of thyself? 23He said, I am the voice of one crying in the wilderness, Make straight the way of the Lord, as said Isaiah the prophet. 24And they had been sent from the Pharisees. 25And they asked him, and said unto him, Why then baptizest thou, if thou art not the Christ, neither Elijah, neither the prophet?
