Zophar is the third of Job’s friends to speak to him, and Zophar is offended.
In their belief system, bad things don’t happen to good people. If something bad has happened to you, it’s because you have sinned.
Job really doesn’t deny that he is a sinner, only that his sins do not merit the misery he is suffering (note 10:13-17). God has gone overboard.
This is what offends Zophar. Even though he cannot cite (or at least doesn’t) a specific sin of Job’s, he believes Job has made light of his own sin. The crusty Zophar overstates Job’s evaluation of himself, and overstates the nature of Job’s sins. In the end, he calls Job to “turn to God” and things will “turn around.”
As you read this, do you get the feeling that everyone is talking, but no one is listening?
