Proverbs 30:6

“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.

“Whatever I am commanding you, you shall be careful to do; you shall not add to nor take away from it.

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.
