John 1:21-25

They asked him, “What then? Are you Elijah?” And he said, “I am not.” “Are you the [promised] Prophet?” And he answered, “No.” [Deut 18:15, 18; Mal 4:5] Then they said to him, “Who are you? Tell us, so that we may give an answer to those who sent us. What do you say about yourself?” He said, “I am THE VOICE OF ONE SHOUTING IN THE WILDERNESS, ‘MAKE STRAIGHT THE WAY OF THE LORD,’ as the prophet Isaiah said.” [Is 40:3] Now they had been sent from the Pharisees. They asked him, “Why then are you baptizing, if you are not the Christ, nor Elijah, nor the Prophet?”
