Matthew Henry on 2 Peter 2:10–end
The apostle's design being to warn us of, and arm us against, seducers, he now returns to discourse more particularly of them, and give us an account of their character and conduct, which abundantly justifies the righteous Judge of the world in reserving them in an especial manner for the most severe and heavy doom, as Cain is taken under special protection that he might be kept for uncommon vengeance. But why will God thus deal with these false teachers? This he shows in what follows.

Nothing less than this does the religion of Christ require.
John Gill on 2 Peter 2:21
For it had been better for them,.... Not that ignorance is good, or to be excused; but it would have been a lesser evil, and not so much aggravated:
not to have known the way of righteousness; the same with "the way of truth", 2 Peter 2:2, and "the right way", 2 Peter 2:15, the Gospel, which points out the way and method of a sinner's justification before God, which is not by the works of the law, but by the righteousness of Christ imputed to them, and received by faith; and which teaches men to live soberly, righteously, and godly; and a large, notional, though not an experimental knowledge, these apostates had of the word and doctrine of righteousness, and indeed of the whole of the Chris…
