Bildad has progressed beyond calling Job to account for his unconfessed sins to charging Job with being evil and not knowing God.  Job admits that has gone astray but says that his error is his concern alone.  Job knows that God has allowed everything to happen. 

Job relates in chapter 18 that he not only has lost all his wealth, possessions, and children, he has lost his friends, prestige, and honor.  Parts of his skin are eaten away.  He is exposed to the elements. Since he is in the city dump there are possible fires there and the stench must be almost unbearable.

In chapter 19 Job relates how he suffers from the words of his "friends". No one comes to his aid. In fact he is deserted by brothers, acquaintances, kinsmen, friends, servants.  At this point we may wonder what has become of Job's wife.  Last we heard of her was when she encouraged Job to curse God and die. He says, "My breath is offensive to my wife?"  He must have had some contact with her during this time. 

While in the rock bottom of this pit, Job has an “epiphany moment”!  He speaks with extreme confidence. 

“I know that my Redeemer lives, and that in the end he will stand upon the earth. And after my skin has been destroyed, yet in my flesh I will see God; I myself will see him with my own eyes – I and not another. How my heart yearns within me!”

Earlier, Job questioned if there is life after death. His question is answered while he is in the depths of despair. Job knew!!! He knew about the Redeemer and he knew about everlasting life. He knew that that he would see God, and he would see God in his flesh. His skin, his human body will decay. Yet he will see God in the flesh. The Hebrew word flesh has a related Hebrew word that means fresh, full of vitality, cheerful, announcing good news.  Ponder this...Job will be resurrected in the millennium!  Job will have a fresh body announcing good news as he rules in the millennium.

When Zophar responds again in chapter 20 he seems to be displaying an "oh, poor me" attitude.  In light of all that Job is going through, Zophar is upset by Job's rebuke.

There is a great line in Job 21.
"Can anyone teach knowledge to God..." 
Sometimes we want to tell God what to do, like we know what's best for us.  HA!
