Isaiah 59:20-21

20 "Then a Redeemer will come to Tziyon, to those in Ya'akov who turn from rebellion." So says ADONAI.
21 "And as for me," says ADONAI, "this is my covenant with them: my Spirit, who rests on you, and my words which I put in your mouth will not depart from your mouth or from the mouth of your children, or from the mouth of your children's children, now or ever," says ADONAI.
