These are murmurers, complainers, walking after their own lusts; and their mouth speaketh great swelling words, having men's persons in admiration because of advantage.
Murmurers - muttering complains against God's ordinances and ministers in church and state. Compare Jude 1:8; Jude 1:15.
Complainers - never satisfied with their lot (Numbers 11:1: cf. the penalty, Deuteronomy 28:47-48). Walking after their own lusts - (Jude 1:18.) The secret of murmuring and complaining is the restless insatiability of desires.
Great swelling words - (2 Peter 2:18.)
Men's persons - mere outward rank.
Because of advantage - for the sake of what they gain from them. While they talk great swelling words, they are really mean and fawning toward those of wealth.
