Through his eight times of speaking to his three friends, Job exposed himself, exposing many negative things concerning himself.
Job exposed himself as being self-righteous (6:30; 9:20; 27:5-6; 32:1). He was righteous in his own eyes, and he held fast to his righteousness.
Job also exposed himself as a person who was full of reasons. A self-righteous person is always ready to give many reasons regarding his situation.
Job blamed his friends for not understanding him and for not sympathizing with him in love. His friends did not sympathize with him, but neither did he sympathize with them.
In his speaking to his friends, Job complained that God was not fair in treating him in an unexplainable, severe way.
Job felt that there was a case between him and God. He expected and waited to clear up his case with God, even if this meant "taking God to court."
Job's speaking exposed him as being a person who knew God only in the vain knowledge inherited from tradition. Such knowledge was altogether objective.
