For if God did not spare the angels who sinned, but threw them into hell and locked them up in chains in utter darkness, to be kept until the judgment,
You also know that the angels who did not keep within their proper domain but abandoned their own place of residence, he has kept in eternal chains in utter darkness, locked up for the judgment of the great Day.
Then I saw another powerful angel descending from heaven, wrapped in a cloud, with a rainbow above his head; his face was like the sun and his legs were like pillars of fire.
The angel then threw him into the abyss and locked and sealed it so that he could not deceive the nations until the one thousand years were finished. (After these things he must be released for a brief period of time.)
