¹⁸ *I* testify to every one who hears the words of the prophecy of this book, If any one shall add to these things, God shall add to him the plagues which are written in this book.

¹⁹ And if any one take from the words of the book of this prophecy, God shall take away his part from the tree of life, and out of the holy city, which are written in this book.
