Комментарий к Ийова 35:15

And now you should know that this visitation [of His Wrath upon you is nothing according [compared] to your many iniquities.

As 'the greatest man in all the East', Job should have ensured that justice was properly administered in his society: this was his mission from God. Had he used his wealth and influence to organize a campaign against crime, there would have been no rustlers and gangs of bandits to take off his livestock. But when Job failed to recognize the providential nature of the loss of his own livestock, God's anger was so aroused that he brought the further afflictions down upon him, namely, the death of his children and his sickness.
He should have realized that he himself was the cause of everything that had happened to him. His possessions were stolen because he had not wiped out crime; his children were killed because he did not take this to heart and make amends for his sin; and he was also the cause of his own body's suffering because of his luxurious and indulgent life-style.
According to Malbim's interpretation, Elihu appears to be accusing Job of being the sort of righteous person who only cares for himself. He is scrupulous about what he himself does but is less concerned with the problems and shortcomings of society: politics are beneath him.
