Jude 1:7, 10

just as Sodom and Gomorrah and the adjacent cities, since they in the same way as these angels indulged in gross immoral freedom and unnatural vice and sensual perversity. They are exhibited [in plain sight] as an example in undergoing the punishment of everlasting fire. [Gen 19:1-29]

But these men sneer at anything which they do not understand; and whatever they do know by [mere] instinct, like unreasoning and irrational beasts—by these things they are destroyed.
