John 1:21-23

1:21 So they asked him, “Then who are you? Are you Elijah?” He said, “I am not!” “Are you the Prophet?” He answered, “No!” 1:22 Then they said to him, “Who are you? Tell us so that we can give an answer to those who sent us. What do you say about yourself?”

1:23 John said, “I am the voice of one shouting in the wilderness, ‘Make straight the way for the Lord,’ as Isaiah the prophet said.”
