Matthew Poole and continuators on 2 Peter 2:13

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

Under this general Term, all the several Sins they are charged with, are comprehended.

This is said to aggravate their Sin, and signifies either their Impudence in it, that they had cast off all Shame, and practised their Luxury by Day-light, whereas ordinary Sinners are wont to chuse the Night for such Works of Darkness, Rom. 13.12, 13. and 1 Thess. 5.7. Or their Security, that they spent the Day of their Life in their Pleasures, placing their Happiness in present Enjoyments, unmindful of a future Reckoning, and an eternal State.

Not only altogether polluted themselves, but such as defile others, and are Blemishes to the Church whereof they profess themselves Members.

Some read Agapais instead of Apatais, leaving out the Pronoun, rendred, their own; understand this of the Love-Feasts, in which they luxuriously gorged themselves. This might well agree with Iude 12. but that the generality of Greek Copies read Apatais, which we turn, Deceivings, i. e. either Errors, taking the word passively, q. d. they do but make a Sport of Sin, and please themselves with it. And this agrees too with Iude 12. feeding themselves without fear: Or Cheatings, or Imposings upon others (taking Deceivings actively, q. d. they sport themselves while they so finely deceive you, pretending Love in their Feasting with you, when they do it only to gratifie their Appetites; or sporting themselves, and making merry with what they have cheated you of.

Viz. In your Feasts of Charity, with the specious Pretence of which they covered their Naughtiness.
