actully God lambasts Job with question after questioned designed to humiliate him. for example:
Job 38:21
Do you know it, because you were born then, or because the number of your days is great?
not just questions that Job obviously can't answer, but biting, sarcastic criticism of the posture Job has taken, as though Job by complaining God seemed to have treated him unfairly, was making himself equal to God. ((precisely the opposite of the advice in Philippians))
this is exactly Elihu's criticism of Job as well - who chided Job not to think to question God, even in his trials, even when they made no sense to him - specifically because Job, a man, is far beneath God and comparatively ignorant.
God in turn relentlessly accosts Job with the stark contrast of his mortal inadequacy and the LORD's omniscient, limitless power - including explicitly accusing Job of thinking to justify himself by accusing God, exacothe same thing which angered Elihu.
and the other thing which angered Elihu? that Jobs friends had found no basis, but accused Job regardless. the LORD says the same: that they had spoken falsely of Job.
christoph, i don't understand why you think Elihu is wicked. i think he is a picture of Christ here, his dialogue being placed between the words of men and the words of God, and mediating, and declaring the words of God before the judgement is spoken.
