Matthew Poole and continuators on Jude 1:16

16 These are murmurers, complainers , walking after their own lusts ; and their mouth speaketh great swelling words of vanity, having mens persons in admiration because of advantage.

Either these two words signify the same thing; or murmurers may be meant with relation to Gods Decrees, Laws, Providences, and his ordinations in the Church or State, 1 Cor. 10.10. and complainers with respect to their own condition with which they were discontented.

Minding neither the Law of God nor Man, but making their Lusts their Law, and being wholly subject to them, led by them, 2 Pet. 2.10.

Though they were meer Slaves to their own Lusts, yet they would speak big, and use high and exotick strains in their Language, that they might be applauded and admired, see 2 Pet. 2.18.

Flattering and magnifying the greater and richer sort of Men, not considering what they were, so they could gain them to their party, or get Gain by them.
