John 1:19-21

19 This is what John publicly stated when the Jewish leaders sent priests and Levites from Jerusalem to ask him, “Who are you?”

20 John declared plainly and clearly without hesitation, “I am not the Messiah.”

21 “So then, who are you?” they asked. “Elijah?” “No, I'm not,” he answered. “Are you the Prophet?”[7] “No,” he replied.
