Thematic Bible: Denunciations against those who add to, or take from

I [personally solemnly] warn everyone who listens to the statements of the prophecy [the predictions and the consolations and admonitions pertaining to them] in this book: If anyone shall add anything to them, God will add and lay upon him the plagues (the afflictions and the calamities) that are recorded and described in this book. And if anyone cancels or takes away from the statements of the book of this prophecy [these predictions relating to Christ's kingdom and its speedy triumph, together with the consolations and admonitions or warnings pertaining to them], God will cancel and take away from him his share in the tree of life and in the city of holiness (purity and hallowedness), which are described and promised in this book.
