I really didn't want to get embroiled in this discussion, but based upon the above, I feel I must.
The Bible was NOT written for, nor based upon, any particular period in history - it was not intended as a historical, cultural, issues of the day secular, book. Instead, it was written by God to expressly to teach of Christ as Saviour, and of His timeless eternal truths, which transcend any given time period. The Bible should be perceived as being standalone: its own dictionary, fully integrated across all chapter and verse, a glossary of terms, a cross reference, and a self-use instructional manual - fully self-contained, needing no addition for its mission beyond what is already there.

[2Ti 3:16-17 KJV]
16 All scripture [is] given by inspiration of God, and [is] profitable for doctrine, for reproof, for correction, for instruction in righteousness:
17 That the man of God may be perfect, thoroughly furnished unto all good works.
