Revelation 20:2-3

The Thousand Years and the Final Judgment

2 And he laid hold on the dragon, that old serpent, which is the devil, and Satan, and bound him a thousand years,

3 and cast him into the bottomless pit , and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
