Revelation 22:17-19

17Both the Spirit and the bride say, “Come!” Let anyone who hears, say, “Come!” Let the one who is thirsty come. Let the one who desires take the water of life freely.

18I testify to everyone who hears the words of the prophecy of this book: If anyone adds to them, God will add to him the plagues that are written in this book.

19And if anyone takes away from the words of the book of this prophecy, God will take away his share of the tree of life and the holy city, which are written about in this book.
