2 Peter 2:1-4

In the past there arose false prophets among God’s people, just as there will continue to be false teachers who will secretly infiltrate in your midst to divide you, bringing with them their destructive heresies. They will even deny the Master, who paid the price for them, bringing swift destruction on themselves. Many will follow immoral lifestyles. Because of these corrupt false teachers, the way of truth will be slandered. They are only out for themselves, ready to exploit you for their own gain through their cunning arguments. Their condemnation has been a long time coming. But their destruction does not slumber or sit idly by, for it is sure to come. Now, don’t forget, God had no pity for the angels when they sinned but threw them into the lowest, darkest dungeon of gloom and locked them in chains, where they are firmly held until the judgment of torment.
