Isaiah 59:20-21

20The Lord says, ‘A Redeemer will come to Zion. He will come to save Jacob's people who turn away from their sins.’

21The Lord says, ‘This is the covenant that I make with those people. My Spirit is now with you, and he will not leave you. I have put my words into your mouth, and they will always be with you. They will continue to be in the mouths of your children, and your descendants for ever.’ That is what the Lord says.
