Revelation 22:17-19

17The Spirit and the bride say, “Come!” Let those who hear this say, “Come!” Let those who are thirsty come! Let those who want the water of life take it as a gift.

18I warn everyone who hears the words of the prophecy in this book: If anyone adds anything to this, God will strike him with the plagues that are written in this book.

19If anyone takes away any words from this book of prophecy, God will take away his portion of the tree of life and the holy city that are described in this book.
