19 And this is the testimony of John, when the Jews sent priests and Levites from Jerusalem to ask him, “Who are you?” 20 He confessed, he did not deny, but confessed, “I am not the Christ.” 21 And they asked him, “What then? Are you Elijah?” He said, “I am not.” “Are you the prophet?” And he answered, “No.” 22 They said to him then, “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 in the wilderness, ‘Make straight the way of the Lord,’ as the prophet Isaiah said.”
