2 Peter 2:4-5

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. And he did not spare the former world in the days of Noah when he sent a flood to destroy a depraved world (although he protected Noah, the preacher of righteousness, along with seven members of his family).
