John 1:6-8, 19-28
1:6 There was a man sent from God, whose name was John.
1:7 He came as a witness to testify to the light, so that all might believe through him.
1:8 He himself was not the light, but he came to testify to the light.
1:19 This is the testimony given by John when the Jews sent priests and Levites from Jerusalem to ask him, "Who are you?"
1:20 He confessed and did not deny it, but confessed, "I am not the Messiah."
1:21 And they asked him, "What then? 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? Let us have an answer for those who sent us. What do you say about yourself?"
1:23 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.
1:24 Now they had been sent from the Pharisees.
1:25 They asked him, "Why then are you baptizing if you are neither the Messiah, nor Elijah, nor the prophet?"
1:26 John answered them, "I baptize with water. Among you stands one whom you do not know,
1:27 the one who is coming after me; I am not worthy to untie the thong of his sandal."
1:28 This took place in Bethany across the Jordan where John was baptizing.
