Jude 1:7, 10

Also remember the cities of Sodom and Gomorrah and the other towns around them. In the same way they were full of sexual sin and people who desired sexual relations that God does not allow. They suffer the punishment of eternal fire, as an example for all to see.

But these people speak against things they do not understand. And what they do know, by feeling, as dumb animals know things, are the very things that destroy them.
