Revelation 22:17-19

17And the Spirit and the bride say, Come. And let him that hears say, Come. And let him that is athirst come; he that will, let him take [the] water of life freely.

18I testify to every one who hears the words of the prophecy of this book, If any one shall add to these things, 1God shall add to him the plagues which are written in this book.

19And if any one take from the words of the book of this prophecy, 2God shall take away his part from the tree of life, and out of the holy city, which are written in this book.
