Jude 1:4-7

4For certain men have crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ. 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
