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.

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.

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

tn Grk “written about.”

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.

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.

tc Most later witnesses (P Ψ 𝔐 sy) have θεόν (theon, “God”) after δεσπότην (despotēn, “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 (despotēs) was used especially of God (cf. BDAG 220 s.v. 1.b.). The earlier and better witnesses (𝔓72, 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, despotēs) 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.

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
