Jude 1:5-7

I’m laying this out as clearly as I can, even though you once knew all this well enough and shouldn’t need reminding. Here it is in brief: The Master saved a people out of the land of Egypt. Later he destroyed those who defected. And you know the story of the angels who didn’t stick to their post, abandoning it for other, darker missions. But they are now chained and jailed in a black hole until the great Judgment Day. Sodom and Gomorrah, which went to sexual rack and ruin along with the surrounding cities that acted just like them, are another example. Burning and burning and never burning up, they serve still as a stock warning.
