Isaiah 66:23-24

23“And it will come to pass, that from one New Moon to another, and from one Shabbat to another, all flesh will come to bow down before Me,” says Adonai.

24“As they leave, they will look on the corpses of the people who rebelled against Me. For their worm will not die, and their fire will not be quenched, and they will be a horror to all flesh.”
