Revelation 20:1-3 Then I saw an angel coming down from Heaven, having the key of the bottomless pit, and upon his arm he carried a great chain.

WNT⁽ⁱ⁾ ¹ Then I saw an angel coming down from Heaven, having the key of the bottomless pit, and upon his arm he carried a great chain. ² He laid hold of the Dragon--the ancient serpent--who is the Devil and the Adversary, and bound him for a thousand years, and hurled him into the bottomless pit. ³ He closed the entrance and put a seal upon him in order that he might be unable to lead the nations astray any more until the thousand years were at an end. Afterwards he is to be set at liberty for a short time.
