Isaiah 66:24

The picture of restoration is completed with the thought of the judgment upon the wicked (similarly Isaiah 48:22; Isaiah 57:21), who are here thought of as having been slain in battle by Jehovah (Isaiah 66:15). Their worm, etc.] These words may be intended to refer only to the literal destruction of their corpses, or may also include the torment of the spirits of the ungodly. Jewish interpretation adopted the latter view (Sir 7:17; Jdt 16:17), and it appears also to have the sanction of our Lord's teaching (Mark 9:43).
