Isaiah 59:20-21

New Catholic Bible

²⁰ He will come as a redeemer to Zion,
    and to those in Jacob who cease to rebel.
    This is the word of the Lord.
²¹ As for me, says the Lord,
    this is my covenant with them:
my Spirit which rests upon you
    and my words that I have put into your mouth
will not depart from 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 forevermore.
