Revelation 20:1-3

New Revised Standard Version Catholic Edition

The Thousand Years

20 Then I saw an angel coming down from heaven, holding in his hand the key to the bottomless pit and a great chain. ² He seized the dragon, that ancient serpent, who is the Devil and Satan, and bound him for a thousand years, ³ and threw him into the pit, and locked and sealed it over him, so that he would deceive the nations no more, until the thousand years were ended. After that he must be let out for a little while.
