Jude 1:6

(Pe2 2:4.) kept not their first estate--Vulgate translates, "their own principality," which the fact of angels being elsewhere called "principalities," favors: "their own" implies that, instead of being content with the dignity once for all assigned to them under the Son of God, they aspired higher. ALFORD thinks the narrative in Gen 6:2 is alluded to, not the fall of the devil and his angels, as he thinks "giving themselves over to fornication" (Jde 1:7) proves; compare Greek, "in like manner to these," namely, to the angels (Jde 1:6). It seems to me more natural to take "sons of God" (Gen 6:2) of the Sethites, than of angels, who, as "spirits," do not seem capable of carnal connection. The parallel, Pe2 2:4, plainly refers to the fall of the apostate angels. And "in like manner to these," Jde 1:7, refers to the inhabitants of Sodom and Gomorrah, "the cities about them" sinning "in like manner" as "they" did [ESTIUS and CALVIN]. Even if Greek "these," Jde 1:7, refer to the angels, the sense of "in like manner as these" will be, not that the angels carnally fornicated with the daughters of men, but that their ambition, whereby their affections went away from God and they fell, is in God's view a sin of like kind spiritually as Sodom's going away from God's order of nature after strange flesh; the sin of the apostate angels after their kind is analogous to that of the human Sodomites after their kind. Compare the somewhat similar spiritual connection of whoremongers and covetousness. The apocryphal book of Enoch interprets Gen 6:2 as ALFORD. But though Jude accords with it in some particulars, it does not follow that he accords with it in all. The Hebrews name the fallen angels Aza and Azael. left--on their own accord. their own--Greek, "their proper." habitation--heaven…

We have here, I. An account of the penman of this epistle, a character of the church, the blessings and privileges of that happy society (Jde 1:1, Jde 1:2). II. The occasion of writing this epistle (Jde 1:3). III. A character of evil and perverse men, who had already sprung up in that infant state of the church, and would be succeeded by others of the like evil spirit and temper in after-times (Jde 1:4). IV. A caution against hearkening to and following after such, from the severity of God towards the unbelieving murmuring Israelites at their coming out of Egypt, the angels that fell, the sin and punishment of Sodom and Gomorrah (Jde 1:5-7). V. To these the apostle likens the seducers against whom he was warning them, and describes them at large, (Jde 1:8-10, inclusive). VI. Then (as specially suitable to his argument) he cites an ancient prophecy of Enoch foretelling and describing the future judgment (Jde 1:14, Jde 1:15). VII. He enlarges on the seducers' character, and guards against the offence which honest minds might be apt to take at the so early permission of such things, by showing that it was foretold long before that so it must be (Jde 1:16-19). VIII. Exhorts them to perseverance in the faith, fervency in prayer, watchfulness against falling from the love of God, and a lively hope of eternal life (Jde 1:20, Jde 1:21). IX. Directs them how to act towards the erroneous and scandalous (Jde 1:22, Jde 1:23). And, X. Closes with an admirable doxology in the last two verses.

1:6 The angels might refer to the fall of Satan and his angelic followers, but no Old Testament passage clearly describes this event (see study notes on Isa 14:12-17; Ezek 28:12-19). Jude was probably referring to Gen 6:1-4; Jewish tradition understood the “sons of God” in Gen 6 to be wicked angels and viewed their intercourse with women as the cause of their judgment (see 1 Enoch 6–10; see also study notes on 1 Pet 3:19-20; 2 Pet 2:4). Jude later (Jude 1:14-15) quotes directly from 1 Enoch.
