The poetic disputations are set within the prose framework of an ancient legend that originated outside Israel.
This legend concerns Job, a prosperous man of outstanding piety.
The Book of Job may be divided into two sections of prose narrative, consisting of a prologue (chapters 1–2) and an epilogue (chapter 42:7–17), and intervening poetic disputation (chapters 3–42:6).
The prose narratives date to before the 6th century .
Chapters 28 and 32–37 were probably later additions.
The Book of Job’s artful construction accounts for much of its impact.
If Job can reasonably be dated in the time of the patriarchs, it becomes a very real possibility that the Sumerian stories derived from Job via oral tradition, instead of vice versa.
Therefore, because both the Sumerian and the Job stories wrestle with similar questions, liberal scholars conclude the Job story MUST be derivative from the Sumerian stories.
On the other hand, many conservative scholars date the book of Job to 1900-1700 BC, the time period known as the time of the patriarchs, Abraham, Isaac and Jacob.
Liberal scholars insist the Book of Job was written around the 6th or 5th century BC.
They believe that Sumerian stories containing themes similar to the Book of Job were written around 1700 BC.
I believe the Book of Job was written during the time of the patriarchs, 1900 to 1700 BC.
This date makes the most Biblical and historical sense given the evidence, some of which I will list below.
