Jude 1:6-8

6 And the angels which kept not their first estate, but left their own habitation, he has reserved in everlasting chains under darkness unto the judgment of the great day.

7 Even as S’dom [Burning] and ‘Amorah [a ruined heap], and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.

8 Likewise also these [filthy] dreamers defile the flesh, despise dominion, and speak evil of dignities.
