I think that the bible is somewhat of a reliable history book do you disagree?

You need to clarify the question. " Reliability" implies "factual accuracy" but since "facts" (facere-to make) are agreed human constructions for mutual purposes you need to separate agreement about occurence of events from agreement about understandable behavior specific to events whether or not such events occurred.

Which bible?

I have not read all bibles but I would guess that they all have insight to what people believed at the time and how they thought people should behave.
