Apostol § 78e

Woe unto 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 blemishes on 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. And Enoch, the seventh from Adam, prophesied about these men also, saying, “Behold, the Lord cometh with ten thousands of His saints, to execute judgment upon all, to convict all who are ungodly among them of all their ungodly deeds which they have committed in an ungodly way, and of all the harsh things which ungodly sinners have spoken against Him.” These are grumblers, complainers, walking according to their own lusts; and they mouth great swelling words, flattering people to gain advantage.
