Revelation 20:1 Revelation 20:1 And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand. John had seen the dragon, the old serpent, which is the devil and Satan, and his angels, cast out of the Roman papal kingdom and dominion. Revelation 12:7-10 And here John had revealed unto him how the dragon (as a conquered enemy, and wretched captive) is bound, and made a close prisoner for a thousand years, after the destruction of the Roman papal kingdom and dominion.

Secondly, by the emblem of his power and great authority Having the key of the bottomless pit, Revelation 1:18; Revelation 3:7. Thirdly, by the means of executing his great power.
