Jude 1:12-13

These men are hidden reefs [elements of great danger to others] in your love feasts when they feast together with you without fear, looking after [only] themselves; [they are like] clouds without water, swept along by the winds; autumn trees without fruit, doubly dead, uprooted and lifeless; wild waves of the sea, flinging up their own shame like foam; wandering stars, for whom the gloom of deep darkness has been reserved forever.
