John 1:15-28   15. ¶John bare witness of him, and cried, saying, This was he of whom I spake, He that cometh after me is preferred before me: for he was before me. 16. And of his fulness have all we received, and grace for grace. 17. For the law was given by Moses, but grace and truth came by Jesus Christ. 18. No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him. 19. ¶And this is the record of John, when the Jews sent priests and Levites from Jerusalem to ask him, Who art thou? 20. And he confessed, and denied not; but confessed, I am not the Christ. 21. And they asked him, What then? Art thou Elias? And he saith, I am not. Art thou that prophet? And he answered, No. 22. Then said they unto him, Who art thou? that we may give an answer to them that sent us. What sayest thou of thyself? 23. He said, I am the voice of one crying in the wilderness, Make straight the way of the Lord, as said the prophet Esaias. 24. And they which were sent were of the Pharisees. 25. And they asked him, and said unto him, Why baptizest thou then, if thou be not that Christ, nor Elias, neither that prophet? 26. John answered them, saying, I baptize with water: but there standeth one among you, whom ye know not; 27. He it is, who coming after me is preferred before me, whose shoe's latchet I am not worthy to unloose. 28. These things were done in Bethabara beyond Jordan, where John was baptizing.

Acts 19:3-5   3. And he said unto them, Unto what then were ye baptized? And they said, Unto John's baptism. 4. Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus. 5. When they heard this, they were baptized in the name of the Lord Jesus.
