2 Peter 2:13

And shall receive the reward of unrighteousness, as they that count it pleasure to riot in the day time. Spots they are and blemishes, sporting themselves with their own deceivings while they feast with you;

receiving the wages of unrighteousness; people who count it pleasure to revel in the day-time, spots and blemishes, reveling in their deceit while they feast with you;

suffering wrong as the hire of wrong-doing; `men' that count it pleasure to revel in the day-time, spots and blemishes, revelling in their deceivings while they feast with you;

about to receive a reward of unrighteousness, pleasures counting the luxury in the day, spots and blemishes, luxuriating in their deceits, feasting with you,

The harm they will suffer is the wages of their wickedness. They consider it a pleasure to carouse in broad daylight. They are blots and blemishes, reveling in their deception as they feast with you.
