Thematic Bible: Denunciations against those who add to, or take from

I testify to every man who hears the words of the prophecy of this book, if any man should add to them, God will add to him the seven plagues that are written in this book. And if any man takes away from the words of the book of this prophecy, God will take away his part from the tree of life, and from the holy city, the things written in this book.
