For if God spared not the angels that sinned, but cast them down to {c} hell, and delivered them into {d} chains of darkness, to be reserved unto judgment;

(c) So the Greeks called the deep dungeons under the earth, which should be appointed to torment the souls of the wicked in.

(d) Bound them with darkness as with chains: and by darkness he means that most miserable state of life that is full of horror.

People's New Testament

2:4 For if God spared not the angels that sinned. In order to show that judgments on these wicked teachers are sure, Peter cites examples. Even angels when they sinned were subjected to punishment.

But cast them down to hell. The sinning angels were cast out of heaven. The word rendered hell is not Gehenna, but Tartarus, a Greek term used for the place of future punishment.

Delivered them into chains of darkness. Pits of darkness (Revised Version); possibly dungeons of darkness gives the idea. Compare Jude 1:6 Both passages point to a time when angels sinned, fell, and thus became angels of darkness.

Wesley's Notes

2:4 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. Though still those chains do not hinder their often walking up and down seeking whom they may devour.

Jamieson-Fausset-Brown Bible Commentary

4. if-The apodosis or consequent member of the sentence is not expressed, but is virtually contained in 2Pe 2:9. If God in past time has punished the ungodly and saved His people, He will be sure to do so also in our days (compare end of 2Pe 2:3).

angels-the highest of intelligent creatures (compare with this verse, Jude 6), yet not spared when they sinned.

hell-Greek, "Tartarus": nowhere else in New Testament or the Septuagint: equivalent to the usual Greek, "Gehenna." Not inconsistent with 1Pe 5:8; for though their final doom is hell, yet for a time they are permitted to roam beyond it in "the darkness of this world." Slaves of Tartarus (called "the abyss," or "deep," Lu 8:31; "the bottomless pit," Re 9:11) may also come upon earth. Step by step they are given to Tartarus, until at last they shall be wholly bound to it.

delivered-as the judge delivers the condemned prisoner to the officers (Re 20:2).

into chains-(Jude 6). 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. So the ungodly were considered as virtually "in prison," though at large on the earth, from the moment that God's sentence went forth, though not executed till one hundred twenty years after.

Matthew Henry's Concise Commentary

2:1-9 Though the way of error is a hurtful way, many are always ready to walk therein. Let us take care we give no occasion to the enemy to blaspheme the holy name whereby we are called, or to speak evil of the way of salvation by Jesus Christ, who is the Way, the Truth, and the Life. These seducers used feigned words, they deceived the hearts of their followers. Such are condemned already, and the wrath of God abides upon them. God's usual method of proceeding is shown by examples. Angels were cast down from all their glory and dignity, for their disobedience. If creatures sin, even in heaven, they must suffer in hell. Sin is the work of darkness, and darkness is the wages of sin. See how God dealt with the old world. The number of offenders no more procures favour, than their quality. If the sin be universal, the punishment shall likewise extend to all. If in a fruitful soil the people abound in sin, God can at once turn a fruitful land into barrenness, and a well-watered country into ashes. No plans or politics can keep off judgments from a sinful people. He who keeps fire and water from hurting his people, Isa 43:2, can make either destroy his enemies; they are never safe. When God sends destruction on the ungodly, he commands deliverance for the righteous. In bad company we cannot but get either guilt or grief. Let the sins of others be troubles to us. Yet it is possible for the children of the Lord, living among the most profane, to retain their integrity; there being more power in the grace of Christ, and his dwelling in them, than in the temptations of Satan, or the example of the wicked, with all their terrors or allurements. In our intentions and inclinations to commit sin, we meet with strange hinderances, if we mark them When we intend mischief, God sends many stops to hinder us, as if to say, Take heed what you do. His wisdom and power will surely effect the purposes of his love, and the engagements of his truth; while wicked men often escape suffering here, because they are kept to the day of judgment, to be punished with the devil and his angels.
