Personally, I consider the Bible to be a history book as well as a spiritual "self-help" book.
I also find that sometimes to get to the heart of the history it is easier to read a modern English version like the NIV or the Amplied (just to name two). However, if I am wanting to appreciate 16th century poetry, King James version.
The complete title to the book of Ephesians (or the subtitle depending on your point of view) is Paul's Letter to the Church in Ephesus. I always find that Wikipedia has good background information.
