"You shall not add to the word which I command you, nor take from it, that you may keep the commandments of the LORD your God which I command you.

"because you have listened to the voice of the LORD your God, to keep all His commandments which I command you today, to do [what is] right in the eyes of the LORD your God.

"Only be strong and very courageous, that you may observe to do according to all the law which Moses My servant commanded you; do not turn from it to the right hand or to the left, that you may prosper wherever you go.

Do not add to His words, Lest He rebuke you, and you be found a liar.

"teaching them to observe all things that I have commanded you; and lo, I am with you always, [even] to the end of the age." Amen.

For I testify to everyone who hears the words of the prophecy of this book: If anyone adds to these things, God will add to him the plagues that are written in this book;

and if anyone takes away from the words of the book of this prophecy, God shall take away his part from the Book of Life, from the holy city, and [from] the things which are written in this book.
