Jude 1:10-13, 16

But these speak evil of whatever they do not know; and whatever they know naturally, like brute beasts, in these things they corrupt themselves. Woe to them! For they have gone in the way of Cain, have run greedily in the error of Balaam for profit, and perished in the rebellion of Korah. These are spots in your love feasts, while they feast with you without fear, serving only themselves. They are clouds without water, carried about by the winds; late autumn trees without fruit, twice dead, pulled up by the roots; raging waves of the sea, foaming up their own shame; wandering stars for whom is reserved the blackness of darkness forever.

These are grumblers, complainers, walking according to their own lusts; and they mouth great swelling words, flattering people to gain advantage.
