I warn everyone who hears the words of the prophecy of this scroll: if anyone adds to them, God will add to them the plagues described in this scroll,
In context
16“I, Jesus, have sent my angel to testify to you these things for the churches. I am the root and the descendant of David, the bright morning star.” 17The Spirit and the bride say, “Come!” And let the one who hears say, “Come!” Let the one who is thirsty come; let anyone who wishes take the water of life as a gift. 18I warn everyone who hears the words of the prophecy of this scroll: if anyone adds to them, God will add to them the plagues described in this scroll, 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 in the holy city, which are described in this scroll. 20The one who testifies to these things says, “Yes, I am coming soon.” Amen. Come, Lord Jesus!
