1) “At that time Michael will rise – the great Prince, defender of Your people. That will be a time of great distress, unparalleled since nations first came into existence. When that time comes, Your own people will be spared – all those whose names are found written in the Book” (Dn 12:1).
2) “Then I saw an angel come down from Heaven, with the key of the Abyss in his hand and an enormous chain. He overpowered the dragon, that primeval serpent which is the devil and Satan, and chained him up for a thousand years. He hurled him into the Abyss and shut the entrance and sealed it over him, to make sure he would not lead the nations astray again until the thousand years had passed. At that time he must be released, but only for a short while” (Rv 20:1-3).
