Revelation 20:1-3; Revelation 20:10

1 And I saw an angel coming down out of heaven, having the key to the Abyss and holding in his hand a great chain.

2 He seized the dragon, that ancient serpent, who is the devil, or Satan, and bound him for a thousand years.

3 He threw him into the Abyss, and locked and sealed it over him, to keep him from deceiving the nations anymore until the thousand years were ended. After that, he must be set free for a short time.

10 And the devil, who deceived them, was thrown into the lake of burning sulfur, where the beast and the false prophet had been thrown. They will be tormented day and night for ever and ever.
