18 For I testify together [to] everyone who hears the words of the prophecy of this Book: If anyone adds to these things, God will add on him the plagues that have been written in this Book.
19 And if anyone takes away from the words of the Book of this prophecy, God will take away his part out of the Book of Life, and out of the holy city, and [from] the things which have been written in this Book.
