Isaac Asimov wrote a series of short stories about a rather dislikeable man named George Bitternut who claims to have a sort of pet demon, around two centimetres high, whom he can summon to perform minor miracles, often to "help" people he knows, although the effect often isn't what he expected. The name of this demon is Azazel, and he's first introduced as follows:
Oh, Azazel - that's his name - is a friendly demon. I suspect he is looked down upon in his native haunts, for he is extraordinarily anxious to impress me with his powers, except that he won't use them to make me rich, as he should out of decent friendship. He says his powers must be used only to do good to others. [...] He says that his country is kindly, decent, and highly civilized, and he speaks with enormous respect of his ruler whom he won't name but whom he calls merely the All-in-All.
Not his name, of course. Couldn't pronounce his real name, I suppose, but that's what I call him.
"Have you figured out his real name?" I asked, unperturbed by this dire warning.
"Can't! It's unpronounceable by any earthly pair of lips. The translation is, I am given to understand, something like: 'I am the King of Kings; look upon my works, ye mighty, and despair.' It's a lie, of course,said George, staring moodily at his beer. He's small potatoes in his world. That's why he's so cooperative here. In our world, with our primitive technology, he can show off."
Why is the name Azazel considered fitting for this little demon? I'm not much up on Biblical lore, but I looked up Azazel and couldn't see any immediate reflection in the character of a minuscule demon summoned to do miraculous party tricks. Presumably there's some thematic similarity which explains, both in-universe and out of universe, why the name Azazel was given to this demon (by George or by Asimov, respectively).
