Jude 1:10-13

10But these rail at whatsoever things they know not: and what they understand naturally, like the creatures without reason, in these things are they destroyed. 11Woe unto them! for they went in the way of Cain, and ran riotously in the error of Balaam for hire, and perished in the gainsaying of Korah. 12These are they who are hidden rocks in your love-feasts when they feast with you, shepherds that without fear feed themselves; clouds without water, carried along by winds; autumn trees without fruit, twice dead, plucked up by the roots; 13wild waves of the sea, foaming out their own shame; wandering stars, for whom the blackness of darkness hath been reserved for ever.
