Context
15For without dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.
16I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, the bright and morning star.
17And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely.
18For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:
19And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and the things which are written in this book.
20He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus.
21The grace of our Lord Jesus Christ with you all. Amen.
