Job 29 - 31 Job's final words (nearly!)

Job 29

Apparently Job has not had his full say after the little interlude, no doubt somebody who is learned in the book of Job can explain what the interlude is all about - if you share it in comments?

Job now recalls a time, just a few months ago when he was rich, healthy and respected. He used his wealth to defend the innocent, help widows.
He would work on behalf of the blind and the lame 

Job 30 

But now the people who once respected Job now mocked him and men whose fathers once Job would not have employed to train his sheepdogs.

Job is now afflicted and in pain with no respect and no hope 
He has tuned his lyre for mourning and his pipe music has turned to wailing.

Job 31

Job in this chapter pleads his case - 
"I made a covenant with my eyes not to look lustfully at a young woman" 

Job challenges that if he has sinned and been evil then surely God would have seen this.

If Job had sinned by oppressing other people then surely bad things could happen, but actually they have happened with him being innocent 

Obviously these are very heavily edited - the actual speech goes on and on and on!
