This verb means to revel or take luxurious pleasure in something, often with negative connotations of excess or mockery. Second Peter 2:13 condemns false teachers who 'revel in their deceptions while they feast with you.' The term suggests self-indulgent pleasure, sometimes at others' expense. Classical usage included delighting in privileges, exulting over others' misfortunes, or treating things contemptuously. Peter depicts shameless hedonists who luxuriate in their own deceit even during sacred fellowship meals.
