'Themselves' in the Bible

11How terrible it will be for them! For they lived like Cain did , rushed headlong into Balaam's error to make a profit, and destroyed themselves, as happened in Korah's rebellion.

These people are stains on your love feasts. They feast with you without any sense of awe. They are shepherds who care only for themselves. They are waterless clouds blown about by the winds. They are autumn trees that are fruitless, totally dead, and uprooted.
