¹ tn The reference is now to the false teachers.

² tn Grk “dreaming.” The participle ἐνυπνιαζόμενοι (enupniazomenoi, “dreaming”) is adverbial to the pronoun οὗτοι (|outoi, “these”), though the particular relationship is not clear. It could mean, “while dreaming,” “by dreaming,” or “because of dreaming.” This translation has adopted the last option as Jude’s meaning, partially for syntactical reasons (the causal participle usually precedes the main verb) and partially for contextual reasons (these false teachers must derive their authority from some source, and the dreams provide the most obvious base). The participle ἐνυπνιαζόμενοι was sometimes used of apocalyptic visions, both of true and false prophets. This seems to be the meaning here.

³ tn Most likely, the authority of the Lord is in view. This verse, then, echoes the indictment of v. 4: “they deny our Master and Lord, Jesus Christ.”

⁴ tn The construction with the three verbs (“defile, “reject,” and “insult”) involves the particles μέν, δέ, δέ (men, de, de). A more literal (and pedantic) translation would be: “on the one hand, they defile the flesh, on the other hand, they reject authority, and on another hand, they insult the glorious ones.”

⁵ sn The glorious ones refers to angelic beings rather than mere human beings, just as in 2 Pet 2:10 (on which this passage apparently depends). Whether the angelic beings are good or evil, however, is difficult to tell (hence, the translation is left ambiguous). However, both in 2 Pet 2:11 and here, in Jude 9, the wicked angels seem to be in view (for not even Michael insults them).

⁶ tn Or “they should naturally comprehend.” The present tense in this context may have a conative force.

sn They instinctively comprehend. Like irrational animals, these false teachers do grasp one thing – the instinctive behavior of animals in heat. R. Bauckham (Jude, 2 Peter [WBC], 63) notes that “Though they claim to be guided by special spiritual insight gained in heavenly revelations, they are in fact following the sexual instincts which they share with the animals.” Jude’s focus is somewhat different from Peter’s: Peter argued that, like irrational animals who are born to be caught and killed, these men will be destroyed when destroying others (2 Pet 2:12). Jude, however, does not mention the destruction of animals, just that these false teachers will be destroyed for mimicking them.
