If Job didn't utter a sinful word, then obliviously God gives out evil as well as good.
“I say to you that everyone who continues wrathful with his brother will be accountable to the court of justice; but whoever addresses his brother with an unspeakable word of contempt will be accountable to the Supreme Court; whereas whoever says, ‘You despicable fool!’ will be liable to the fiery Gehenna.”—Matthew 5:22.
Guess Job only said Wicked fool. And his wife had to have 10 more children with him.
