John 1:21-25

What do you say about yourself?” He said, “I am the voice of one crying out in the wilderness, ‘Make straight the way of the Lord,’ as the prophet Isaiah said.” (Now they had been sent from the Pharisees.) They asked him, “Then why are you baptizing, if you are neither the Christ, nor Elijah, nor the Prophet?”
