Deuteronomy 12:32

“You shall not add to the word which I am commanding you, nor take away from it, that you may keep the commandments of Yahweh your God which I am commanding you.

Do not add to His words Lest He reprove you, and you be proved a liar.

Then Yahweh said to me, “Son of man, set your heart on and see with your eyes and hear with your ears all that I say to you concerning all the statutes of the house of Yahweh and concerning all its laws; and set your heart on the entrance of the house, with all exits of the sanctuary.

I bear witness 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.

And if anyone takes away from the words of the book of this prophecy, God will take away his part from the tree of life and from the holy city, which are written in this book.
