¹ tn Grk “people.” However, if Jude is indeed arguing that Peter’s prophecy about false teachers has come true, these are most likely men in the original historical and cultural setting. See discussion of this point in the note on the phrase “these men” in 2 Pet 2:12.

² tn “Among you” is not in the Greek text, but is obviously implied.

sn The infiltration referred to by the phrase slipped in among you was predicted by Peter (2 Pet 2:1), Paul (e.g., Acts 20:29-30), and OT prophets.

³ tn Or “in the past.” The adverb πάλαι (palai) can refer to either, though the meaning “long ago” is more common.

⁴ tn Grk “written about.”

⁵ tn Grk “for this condemnation.” τοῦτο (touto) is almost surely a kataphoric demonstrative pronoun, pointing to what follows in vv. 5-18. Otherwise, the condemnation is only implied (in v. 3b) or is merely a statement of their sinfulness (“ungodly” in v. 4b), not a judgment of it.

⁶ tn Grk “debauchery.” This is the same word Peter uses to predict what the false teachers will be like (2 Pet 2:2, 7, 18).

sn Turned the grace of our God into a license for evil. One of the implications that the gospel in the apostolic period was truly a gospel of grace was the fact that the enemies of the gospel could pervert it into license. If it were a gospel of works, no such abuse could be imagined. Along these lines, note Rom 6:1 – “Are we to remain in sin so that grace may increase?” This question could not have even been asked had the gospel been one of works. But grace is easily misunderstood by those who would abuse it.

⁷ tc Most later witnesses (P Ψ Ï sy) have θεόν (qeon, “God”) after δεσπότην (despothn, “master”), which appears to be a motivated reading in that it explicitly links “Master” to “God” in keeping with the normal NT pattern (see Luke 2:29; Acts 4:24; 2 Tim 2:21; Rev 6:10). In patristic Greek, δεσπότης (despoth") was used especially of God (cf. BDAG 220 s.v. 1.b.). The earlier and better witnesses (Ì^72,78 א A B C 0251 33 81 323 1241 1739 al co) lack θεόν; the shorter reading is thus preferred on both internal and external grounds.

sn The Greek term for Master (δεσπότης, despoths) is the same term the author of 2 Peter used (2 Pet 2:1) to describe his Lord when he prophesied about these false teachers. Since δεσπότης is used only ten times in the NT, the verbal connection between these two books at this juncture is striking. This is especially so since both Peter and Jude speak of these false teachers as denying the Master (both using the same verb). The basic difference is that Peter is looking to the future, while Jude is arguing that these false teachers are here now.

⁸ tn The terms “Master and Lord” both refer to the same person. The construction in Greek is known as the Granville Sharp rule, named after the English philanthropist-linguist who first clearly articulated the rule in 1798. Sharp pointed out that in the construction article-noun-καί-noun (where καί [kai] = “and”), when two nouns are singular, personal, and common (i.e., not proper names), they always had the same referent. Illustrations such as “the friend and brother,” “the God and Father,” etc. abound in the NT to prove Sharp’s point. For more discussion see ExSyn 270-78. See also Titus 2:13 and 2 Pet 1:1

⁹ tn Grk “as.”

¹⁰ tn Grk “the towns [or cities] surrounding them.”

¹¹ 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.

¹² tn Or “in the same way as.”

¹³ tn “Angels” is not in the Greek text; but the masculine demonstrative pronoun most likely refers back to the angels of v. 6.

¹⁴ tn Grk “against” (κατά [kata] + genitive). English usage is satisfied with “on” at this point, but the parallel is lost in the translation to some degree, for the end of v. 15 says that this judgment is meted out on these sinners because they spoke against him (κατά + genitive).

¹⁵ tn Or “soul.”

¹⁶ tn Grk “of all their works of ungodliness.” The adverb “thoroughly” is part of the following verb “have committed.” See note on verb “committed” later in this verse.

¹⁷ tn The verb in Greek does not simply mean “have committed,” but “have committed in an ungodly way.” The verb ἀσεβέω (asebew) is cognate to the noun ἀσέβεια (asebeia, “ungodliness”). There is no easy way to express this in English, since English does not have a single word that means the same thing. Nevertheless, the tenor of v. 15 is plainly seen, regardless of the translation.

¹⁸ sn An apparent quotation from 1 En. 1:9. There is some doubt as to whether Jude is actually quoting from the text of 1 Enoch; the text here in Jude differs in some respects from the extant text of this pseudepigraphic book. It is sometimes suggested that Jude may instead have been quoting from oral tradition which had roots older than the written text.
