A powerful winged angel in armor stands on a chained dragon amidst glowing clouds, holding a large key in a dramatic fantasy digital painting.

The scene where an angel imprisons the dragon, identified as Satan, is found in the Book of Revelation, specifically in chapter 20. This event is part of the apocalyptic vision of the end times. The scene in Revelation 20:1–3 The biblical text describes the event with the following details: An angel is seen descending from heaven, holding a great chain and the key to the abyss (or "bottomless pit"). The angel seizes the dragon, referred to as "the ancient serpent, who is the devil and Satan," and binds him with the chain for a thousand years. The dragon is then thrown into the abyss, which the angel locks and seals shut. This is done to prevent Satan from deceiving the nations during the thousand-year period. The passage states that after the thousand years are completed, Satan must be released for a short time. See more
