Jude 1:5-11

5I will therefore put you in remembrance, though ye once knew this, that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not. 6And the angels who kept not their proper abode, but left their own habitation, he hath reserved in everlasting chains under darkness to the judgment of the great day.1 7Even as Sodom and Gomorrah, and the cities about them in like manner, giving themselves over to gross immorality, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.2

8Likewise also thesefilthydreamers defile the flesh, despise dominion, and speak evil of dignities. 9Yet Michael the archangel, when contending with the devil he disputed about the body of Moses, dared not bring against him a railing accusation, but said, The Lord rebuke thee. 10But these speak evil of those things which they know not: but what they know naturally, as brute beasts, in those things they corrupt themselves. 11Woe to them! for they have gone in the way of Cain, and run greedily after the error of Balaam for reward, and perished in the gainsaying of Korah.
