Saying: What thou seest, write in a book, and send to the seven churches which are in Asia, to Ephesus, and to Smyrna, and to Pergamus, and to Thyatira, and to Sardis, and to Philadelphia, and to Laodicea.
Have in mind therefore in what manner thou hast received and heard: and observe, and do penance. If then thou shalt not watch, I will come to thee as a thief, and thou shalt not know at what hour I will come to thee.
For I testify to every one that heareth the words of the prophecy of this book: If any man shall add to these things, God shall add unto him the plagues written in this book.
And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from these things that are written in this book.
