20:10 are. The beast and the false prophet are thus still imprisoned in the lake of fire over a thousand years after first being cast into it (Revelation 19:20). These two are actually men, of course, even though Satanically controlled men. Presumably their human bodies will be consumed by the flames when they are first cast into them, but their souls will still be there a thousand years later when Satan joins them, and they will all continue there forever. It is probable, though not explicitly so stated, that all Satan’s demonic hosts will be cast there simultaneously with him (note Matthew 25:41).
