5. I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not.

5. Commonefacere autem vos volo, quum istud semel noveritis, quod Dominus postquam ex terra Egypti populum servaverat, postea non credentes perdidit.

6. And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.

6. Angelos vero qui principatum (vel, initium) suum non servaverant, sed reliquerant suum domicilium, judicium magnae diei vinculis aeternis sub caligine servavit.

7. Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.

7. Quemadmodum Sodoma et Gomorrha, et qae circum erant urbes, quum simili modo scortatae essent, et abiissent post carnem alienam, propositae sunt ignis aeterni judicium sustinentes.

5. I will therefore put you in remembrance, or, remind you. He either modestly excuses himself, lest he should seem to teach as it were the ignorant things unknown to them; or, indeed, he openly declares in an emphatical manner, (which I approve more of,) that he adduced nothing new or unheard of before, in order that what he was going to say might gain more credit and authority. I only recall, he says, to your mind what you have already learnt. As he ascribes knowledge to them, so he says that they stood in need of warnings, lest they should think that the labor he undertook towards them was superfluous; for the use of God's word is not only to teach what we could not have otherwise known, but also to rouse us to a serious meditation of those things which we already understand, and not to suffer us to grow torpid in a cold knowledge.

Now, the meaning is, that after having been called by God, we ought not to glory carelessly in his grace, but on the contrary, to walk watchfully in his fear; for if any trifles thus with God, the contempt of his grace will not be unpunished. And this he proves by three examples. He first refers to the vengeance which God executed on those unbelievers, whom he had chosen as his people, and delivered by his power. Nearly the same reference is made by Paul in the tenth chapter of the First Epistle to the Corinthians. The import of what he says is, that those whom God had honored with the greatest blessings, whom he had extolled to the same degree of honor as we enjoy at this day, he afterwards severely punished. Then in vain were all they proud of God's grace, who did not live in a manner suitable to their calling.

The word people is by way of honor taken for the holy and chosen nation, as though he had said that it availed them nothing, that they by a singular favor had been taken into covenant. By calling them unbelieving, he denotes the fountain of all evils; for all their sins, mentioned by Moses, were owing to this, because they refused to be ruled by God's word. For where there is the subjection of faith, there obedience towards God necessarily appears in all the duties of life.

6. And the angels. This is an argument from the greater to the less; for the state of angels is higher than ours; and yet God punished their defection in a dreadful manner. He will not then forgive our perfidy, if we depart from the grace unto which he has called us. This punishment, inflicted on the inhabitants of heaven, and on such superior ministers of God, ought surely to be constantly before our eyes, so that we may at no time be led to despise God's grace, and thus rush headlong into destruction.

The word arche in this place, may be aptly taken for beginning as well as for principality or dominion. For Jude intimates that they suffered punishment, because they had despised the goodness of God and deserted their first vocation. And there follows immediately an explanation, for he says that they had left their own habitation; for, like military deserters, they left the station in which they had been placed.

We must also notice the atrocity of the punishment which the Apostle mentions. They are not only free spirits but celestial powers; they are now held bound by perpetual chains. They not only enjoyed the glorious light of God, but his brightness shone forth in them, so that from them, as by rays, it spread over all parts of the universe; now they are sunk in darkness. But we are not to imagine a certain place in which the devils are shut up, for the Apostle simply intended to teach us how miserable their condition is, since the time they apostatized and lost their dignity. For wherever they go, they drag with them their own chains, and remain involved in darkness. Their extreme punishment is in the meantime, deferred until the great day comes.

7. Even as Sodom and Gomorrha. This example is more general, for he testifies that God, excepting none of mankind, punishes without any difference all the ungodly. And Jude also mentions in what follows, that the fire through which the five cities perished was a type of the eternal fire. Then God at that time exhibited a remarkable example, in order to keep men in fear till the end of the world. Hence it is that it is so often mentioned in Scripture; nay, whenever the prophets wished to designate some memorable and dreadful judgment of God, they painted it under the figure of sulfurous fire, and alluded to the destruction of Sodom and Gomorrha. It is not, therefore, without reason that Jude strikes all ages with terror, by exhibiting the same view.

When he says, the cities about them in like manner, giving themselves over to fornication, I do not apply these words to the Israelites and the angels, but to Sodom and Gomorrha. It is no objection that the pronoun toutois is masculine, for Jude refers to the inhabitants and not to the places. To go after strange flesh, is the same as to be given up to monstrous lusts; for we know that the Sodomites, not content with the common manner of committing fornication, polluted themselves in a way the most filthy and detestable. We ought to observe, that he devotes them to eternal fire; for we hence learn, that the dreadful spectacle which Moses describes, was only an image of a much heavier punishment.
