Jude 1:16

These are. Jude now returns to his discussion of the false teachers (cf. v. 12; 2 Peter 2:17), implying that they are included among those to whom the prophecy refers as “ungodly.”

Murmurers. Gr. goggustai, “grumblers,” from gogguzō, an onomatopoeic word (pronounced “gongudzō”), “to grumble,” “to mutter.” Compare on 1 Peter 4:9.

Complainers. That is, those who are dissatisfied with their lot and who consequently murmur against God.

After their own lusts. See on 2 Peter 3:3.

Great swelling words. Gr. huperogka (see on 2 Peter 2:18).

Having men’s persons in admiration. Literally, “admiring faces,” that is, showing respect to persons, contrary to Christian ethics (cf. on James 2:1). The false teachers were morally rotten and had no compunction about employing flattery to their own advantage. Such men are not to be trusted, and Jude was careful to warn his readers about their deceptions.
