19 This is the testimony given by John when the Jews sent priests and Levites from Jerusalem to ask him, "Who are you?"
20 He confessed and did not deny it, but confessed, "I am not the Messiah."
21 And they asked him, "What then? Are you Elijah?" He said, "I am not." "Are you the prophet?" He answered, "No."
22 Then they said to him, "Who are you? Let us have an answer for those who sent us. What do you say about yourself?"
23 He said, "I am the voice of one crying out in the wilderness, "Make straight the way of the Lord,' " as the prophet Isaiah said.
