⁴ sn Israel’s devotion to her idols is inordinate, irrational, and self-destructive.

¹ sn The irrational arrogance of the Assyrians (v. 15) will prompt the judgment about to be described.

² sn Paul had to be carried. Note how the arrest really ended up protecting Paul. The crowd is portrayed as irrational at this point.

² sn The botanical imagery, when juxtaposed with the preceding rhetorical questions, vividly depicts and emphasizes how the Israelites have perverted justice and violated the created order by their morally irrational behavior.

¹ sn “You’ve lost your mind!” Such a response to the miraculous is not unusual in Luke-Acts. See Luke 24:11; Acts 26:25. The term μαίνομαι (mainomai) can have the idea of being “raving mad” or “totally irrational” (BDAG 610 s.v.). It is a strong expression.

² sn The image of a cup that brings dizziness is that of drunkenness. The Lord will force the nations to drink of his judgment and in doing so they will become so intoxicated by his wrath that they will stumble and become irrational.

¹ sn This proverb introduces the danger of becoming a victim of the king’s wrath (cf. CEV “if the king becomes angry, someone may die”). A wise person knows how to pacify the unexpected and irrational behavior of a king. The proverb makes the statement, and then gives the response to the subject.

¹ 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.

³ sn The Hebrew term translated lunatic applies to anyone who exhibits irrational behavior. It was used for example of David, who drooled and scratched on the city gate to convince Achish not to arrest him as a politically dangerous threat (1 Sam 21:14). It was often used contemptuously of the prophets by those who wanted to play down the significance of their words (2 Kgs 9:11; Hos 9:7, and here).

⁶ tn This cryptic expression has been variously interpreted. (1) It could involve a simple cognate dative in which case the idea is “they will be utterly destroyed.” But the presence of αὐτῶν (autōn; their, of them) is problematic for this view. Other, more plausible views are: (2) the false teachers will be destroyed at the same time as the irrational beasts, or (3) in the same manner as these creatures (i.e., by being caught); or (4) the false teachers will be destroyed together with the evil angels whom they insult. Because of the difficulties of the text, it was thought best to leave it ambiguous, as the Greek has it.
