And shall receive the reward of unrighteousness - The appropriate recompense of their wickedness in the future world. Such people do not always receive the due recompense of their deeds in the present life; and as it is a great and immutable principle that all will be treated, under the government of God, as they deserve, or that justice will be rendered to every rational being, it follows that there must be punishment in the future state.
As they that count it pleasure to riot in the day-time - As especially wicked, shameless, and abandoned men; for only such revel in open day. Compare the Acts 2:15 note; 1 Thessalonians 5:7 note.
Spots they are and blemishes - That is, they are like a dark spot on a pure garment, or like a deformity on an otherwise beautiful person. They are a scandal and disgrace to the Christian profession.
Sporting themselves - The Greek word here means to live delicately or luxuriously; to revel. The idea is not exactly that of sporting, or playing, or amusing themselves; but it is that they take advantage of their views to live in riot and luxury. Under the garb of the Christian profession, they give indulgence to the most corrupt passions.
With their own deceivings - Jude, in the parallel place, Jude 1:12, has, “These are spots in your feasts of charity, when they feast with you.” Several versions, and a few manuscripts also, here read “feasts” instead of “deceivings,” (ἀγάπαῖς agapais for ἀπάταις apatais.) The common reading, however, is undoubtedly the correct one, (see Wetstein, in loc.); and the meaning is, that they took advantage of their false views to turn even the sacred feasts of charity, or perhaps the Lord’s Supper itself, into an occasion of sensual indulgence. Compare the notes at 1 Corinthians 11:20-22. The difference between these persons, and those in the church at Corinth, seems to have been that these did it at design, and for the purpose of leading others into sin; those who were in the church at Corinth erred through ignorance.
While they feast with you - συνευωχούμενοι suneuōchoumenoi. This word means to feast several together; to feast with anyone; and the reference seems to be to some festival which was celebrated by Christians, where men and women were assembled together, 2 Peter 2:14, and where they could convert the festival into a scene of riot and disorder. If the Lord’s Supper was celebrated by them as it was at Corinth, that would furnish such an occasion; or if it was preceded by a “feast of charity” (notes, Jude 1:12), that would furnish such an occasion. It would seem to be probable that a festival of some kind was connected with the observance of the Lord’s Supper (notes, 1 Corinthians 11:21), and that this was converted by these persons into a scene of riot and disorder.
