1 tn Grk “as.”
2 tn Grk “the towns [or cities] surrounding them.”
3 tn Grk “strange flesh.” This phrase has been variously interpreted. It could refer to flesh of another species (such as angels lusting after human flesh). This would aptly describe the sin of the angels, but not easily explain the sin of Sodom and Gomorrah. It could refer to the homosexual practices of the Sodomites, but a difficulty arises from the use of ἕτερος ({etero"; “strange,” “other”). When this is to be distinguished from ἄλλος (allos, “another”) it suggests “another of a different kind.” If so, would that properly describe homosexual behavior? In response, the language could easily be compact: “pursued flesh other than what was normally pursued.” However, would this find an analogy in the lust of angels (such would imply that angels normally had sexual relations of some sort, but cf. Matt 22:30)? Another alternative is that the focus of the parallel is on the activity of the surrounding cities and the activity of the angels. This is especially plausible since the participles ἐκπορνεύσασαι (ekporneusasai, “having indulged in sexual immorality”) and ἀπελθοῦσαι (apelqousai, “having pursued”) have concord with “cities” (πόλεις, poleis), a feminine plural noun, rather than with Sodom and Gomorrah (both masculine nouns). If so, then their sin would not necessarily have to be homosexuality. However, most likely the feminine participles are used because of constructio ad sensum (construction according to sense). That is, since both Sodom and Gomorrah are cities, the feminine is used to imply that all the cities are involved. The connection with angels thus seems to be somewhat loose: Both angels and Sodom and Gomorrah indulged in heinous sexual immorality. Thus, whether the false teachers indulge in homosexual activity is not the point; mere sexual immorality is enough to condemn them.
4 tn Or “in the same way as.”
5 tn “Angels” is not in the Greek text; but the masculine demonstrative pronoun most likely refers back to the angels of v. 6.
6 tn Grk “wild waves of the sea.”
7 tn Grk “foaming, causing to foam.” The verb form is intensive and causative. BDAG 360 s.v. ἐπαφρίζω suggests the meaning “to cause to splash up like froth, cause to foam,” or, in this context, “waves casting up their own shameless deeds like (dirty) foam.”
8 tn Grk “shames, shameful things.” It is uncertain whether shameful deeds or shameful words are in view. Either way, the picture has taken a decided turn: Though waterless clouds and fruitless trees may promise good things, but deliver nothing, wild sea-waves are portents of filth spewed forth from the belly of the sea.
9 sn The imagery of a star seems to fit the nautical theme that Jude is developing. Stars were of course the guides to sailors at night, just as teachers are responsible to lead the flock through a benighted world. But false teachers, as wayward stars, are not fixed and hence offer unreliable, even disastrous guidance. They are thus both the dangerous reefs on which the ships could be destroyed and the false guides, leading them into these rocks. There is a special irony that these lights will be snuffed out, reserved for the darkest depths of eternal darkness.
10 tn Grk “utter darkness of darkness for eternity.” See note on the word “utter” in v. 6.
