2 Peter 2:4

And the nature of all these deceits is obscure to those who are without the truth. For they think that those demons profit them when they cease to injure, whereas they have no power except to injure. Some one may perchance say that they are therefore to be worshipped, that they may not injure, since they have the power to injure. They do indeed injure, but those only by whom they are feared, whom the powerful and lofty hand of God does not protect, who are uninitiated in the mystery of truth. But they fear the righteous, that is, the worshippers of God, adjured by whose name they depart from the bodies of the possessed: for, being lashed by their words as though by scourges, they not only confess themselves to be demons, but even utter their own names-those which are adored in the temples-which they generally do in the presence of their own worshippers; not, it is plain, to the disgrace of religion, but to the disgrace of their own honour, because they cannot speak falsely to God, by whom they are adjured, nor to the righteous, by whose voice they are tortured. Therefore ofttimes having uttered the greatest howlings, they cry out that they are beaten, and are on fire, and that they are just on the point of coming forth: so much power has the knowledge of God, and righteousness! Whom, therefore, can they injure, except those whom they have in their own power? In short, Hermes affirms that those who have known God are not only safe from the attacks of demons, but that they are not even bound by fate. "The only protection," he says, "is piety, for over a pious man neither evil demon nor fate has any power: for God rescues the pious man from all evil; for the one and only good thing among men is piety."

The angels were in heaven and were thrown into the abyss. But on the other hand, Elijah and Enoch were raised into the kingdom of heaven.

For if God did not spare the angels who sinned, but cast them into chains of gloomy Tartarus10, delivering them to be kept for judgment; and did not spare the ancient world, but preserved Noah, the eighth person, a preacher of righteousness, when he brought …

For if God did not spare the angels who sinned. For many verses here conclude with one ending: The Lord knows how to rescue the godly from trials. For if, he says, God did not spare the angels who sinned, but consigned them to hell …

But He handed over those dragged down by the howls of hell into Tartarus, etc. Another translation has this verse as: But pushing back into the prisons of the darkness of hell, He handed them over to be reserved for punishment in judgment. Therefore, it …

Not without reason does the apostle begin with believers, who are more honorable, but he wishes to show that they are liable to greater condemnation for their sins. They have the advantage of being the first called to apostleship. Therefore, for going astray from the …

There is no place nor state between the height of glory and the depth of misery in which they shall be allowed to rest. If creatures sin in heaven, they must suffer in hell. Sin is the work of darkness, and darkness is the wages of sin.

Cast them down to hell - The bottomless pit, a place of unknown misery. Delivered them - Like condemned criminals to safe custody, as if bound with the strongest chains in a dungeon of darkness, to be reserved unto the judgment of the great day.

For if God spared not the angels that sinned.....

For if God spared not the angels - The angels were originally placed in a state of probation; some having fallen and some having stood proves this. How long that probation was to last to them, and what was the particular test of their fidelity, we know not; nor indeed do we know what was their sin; nor when nor how they fell. St. Jude says they kept not their first estate, but left their own habitation; which seems to indicate that they got discontented with their lot, and aspired to higher honors, or perhaps to celestial domination.

The oldest manuscripts read, "dens," as ALFORD translates: the Greek, however, may, in Hellenistic Greek, mean "chains," as Jude expresses it. They are "reserved" unto hell's "mist of darkness" as their final "judgment" or doom, and meanwhile their exclusion from the light of heaven is begun.

For if God spared not the angels that sinned - The apostle now proceeds to the proof of the proposition that these persons would be punished. It is to be remembered that they had been, or were even then, professing Christians, though they had really, if not in form, apostatized from the faith 2Pe 2:20-22, and a part of the proofs, therefore, are derived from the cases of those who had apostatized from the service of God. He appeals, therefore, to the case of the angels that had revolted. Neither their former rank, their dignity, nor their holiness, saved them from being thrust down to hell; and if God punished them so severely, then false teachers could not hope to escape. The apostle, by the “angels” here, refers undoubtedly to a revolt in heaven - an event referred to in Jud 1:6, and everywhere implied in the Scriptures. When that occurred, however - why they revolted, or what was the number of the apostates - we have not the slightest information, and on these points conjecture would be useless. In the supposition that it occurred, there is no improbability; for there is nothing more absurd in the belief that angels have revolted than that men have; and if there are evil angels, as there is no more reason to doubt than that there are evil men, it is morally certain that they must have fallen at some period from a state of holiness, for it cannot be believed that God made them wicked. But cast them down to hell - Greek ταρταρώσας tartarōsas - “thrusting them down to Tartarus.” The word here used occurs nowhere else in the New Testament, though it is common in the Classical writers.

In the same way, let the convert, or still more the semi-convert, face any one fact that does seem to him to deface the Catholic scheme as a falsehood; and if he faces it long enough he will probably find that it is the greatest …
