Deuteronomy 4:2; Deuteronomy 12:32; Revelation 22:18

yYou shall not add to the word that I command you, nor take from it, that you may keep the commandments of the Lord your God that I command you.

32 1Everything that I command you, you shall be careful to do. pYou shall not add to it or take from it.

18 I warn everyone who hears the words of the prophecy of this book: pif anyone adds to them, God will add to him the plagues described in this book,
