Mercurial:
changeable; volatile; fickle; flighty; erratic:
“Old Testament God”: created man, decided they were too violent without telling mankind that being violent was a bad thing. Destroyed Man with flood. Saved Noah, who then got drunk and cursed an entire tribe of men because its found saw him naked.
God creates a wealth of food in Egypt for seven years, then causes a famine of equal time so Joseph can make bank on stored Egyptian goods.
To punish ALL Egyptians, and not just the ruling class, OT God kills all the Egyptian first-born and when he runs out of them, kills first-born cattle to boot.
Yep, that’s mercurial.
No. “Mercurial” implies doing it without notice, and without telling the creation what is expected of them. The people had plenty of advance warning from prophets—including the antediluvians, from Noah.
And the curse is not because Noah was found naked, but because the one who received the curse did nothing about it (and there is heavy implication that there was lewdness involved in the lack of action); the two tribes that were not cursed did something about it.
Please read the Bible first before making ad hoc claims about its contents.
Enjoy arguing about it when you stand before him in judgement. I already know who wins the argument; I cheated and read the end of the book.
