Revelation 22:17-19

17The Spirit and the bride say, “Come!” Let the one who hears say, “Come!” And let the one who is thirsty come, and the one who desires the water of life drink freely.

18I testify to everyone who hears the words of prophecy in this book: If anyone adds to them, God will add to him the plagues described in this book. 19And if anyone takes away from the words of this book of prophecy, God will take away his share in the tree of life and the holy city, which are described in this book.
