Revelation 22:18

我向一切听见这书上预言的作见证，若有人在这预言上加添什么， 神必将写在这书上的灾祸加在他身上；

wǒ xiàng yí qiè tīng jiàn zhè shū shàng yù yán de zuò jiàn zhèng ， ruò yǒu rén zài zhè yù yán shàng jiā tiān shén me ， shén bì jiāng xiě zài zhè shū shàng de zāi huò jiā zài tā shēn shàng ；

I testify to everyone who hears the words of the prophecy of this book: if anyone adds to them, God will add to him the plagues which are written in this book.
