John 1:23-25

23 John told them in the words of the prophet Isaiah: “I am the voice of a man calling out in the desert: ‘Make the road straight for the Lord.’”

24 In the group of Jews who were sent, there were some Pharisees.

25 They said to John: “You say you are not the Christ. You say you are not Elijah or the Prophet. Then why do you baptize people?”
