John 1:21-23 New American Standard Bible (NASB)

21. They asked him, "What then? Are you Elijah?" And he said, "I am not." "Are you the Prophet?" And he answered, "No."

22. Then they said to him, "Who are you, so that we may give an answer to those who sent us? What do you say about yourself?"

23. He said, "I am a voice of one crying in the wilderness, 'Make straight the way of the Lord,' as Isaiah the prophet said."
