The Book of Job is one of my favorite as well. So very many life lessons to be learned from it.
One of the mysteries of Job is when exactly did he live? Historians do not seem to be able to agree on this, and because of this, it is not easy to read of his life story in context to other peoples of the Bible. One of the best Articles I have found concerning this is linked below:
Apologetics Press - When Did Job Live?
EXCERPT FROM ARTICEL:
Neither the book of Job nor any other book of the Bible indicates forthrightly when God’s servant Job lived upon the Earth. Furthermore, no biblical genealogies with chronological information, such as that found in Genesis 5 and 11, help in approximating the century in which Job lived. Nevertheless, various
clues within the book of Job seem to indicate Job lived sometime after the Flood, but long before the time of Moses.[/QUOTE,/
