John 1:21-25

What do you say about yourself?” He said: “I am ‘The voice of one crying in the wilderness: “Make straight the way of the LORD,” ’ as the prophet Isaiah said.” Now those who were sent were from the Pharisees. And they asked him, saying, “Why then do you baptize if you are not the Christ, nor Elijah, nor the Prophet?”
