11 A curse on them! They have gone in the way of Cain, running uncontrolled into the error of Balaam for reward, and have come to destruction by saying evil against the Lord, like Korah.
12 These men are unseen rocks at your love-feasts, when they take part in them with you, keepers of sheep who without fear take the food of the sheep; clouds without water rushing before the wind, wasted trees without fruit, twice dead, pulled up by the roots,
13 Violent waves of the sea, streaming with their shame, wandering stars for whom the darkest night is kept in store for ever.
