Isaiah 59:20-21

And he will come to Zion as Redeemer, to those in Jacob who turn from transgression, says the LORD. And as for me, this is my covenant with them, says the LORD: my spirit that is upon you, and my words that I have put in your mouth, shall not depart out of your mouth, or out of the mouths of your children, or out of the mouths of your children's children, says the LORD, from now on and forever.
