Revelation 22:17-19

17The Spirit and the bride say, “Come!” And let the one who hears say, “Come!” Let the one who is thirsty come; and let the one who wishes take the free gift of the water of life.

18I warn everyone who hears the words of the prophecy of this scroll: If anyone adds anything to them, God will add to that person the plagues described in this scroll.

19And if anyone takes words away from this scroll of prophecy, God will take away from that person any share in the tree of life and in the Holy City, which are described in this scroll.
