And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand. The destruction of his representatives, the beast and the false prophet, to whom he gave his power, throne, and authority, is followed by the binding of Satan himself a thousand years.
The key of the bottomless pit - transferred from Satan's hands, heretofore permitted to use it in letting loose plagues on the earth: he is now to feel himself the torment which he inflicted on men: his full torment is not until he is cast into "the lake of fire" (Revelation 20:10).
