Q.3: Revelation 22:18–19

18 “For I testify to everyone who hears the words of the prophecy of this Book. If anyone shall add to these things, God shall add to him the plagues that are written in this Book. 19 And if anyone shall take away from the words of the Book of this prophecy, God shall take out his part of the Book of Life, and of the holy City, and from those things which are written in this Book.”
