So.....Job........his old lady thinks he's an idiot.....
The story is told from a man's point of view, too, as pretty much all stories in the OT are.
But think about it from Job's wife's point of view: She has just lost all 10 of her children in a horrific accident. She and Job and now destitute. Now she can do nothing but watch his pain, while her beloved husband wastes away from a disease that makes him foul-smelling and horrible looking.
When she said, "Curse God and die" , maybe she just wanted to end his suffering.
