(Your reply brings to mind another book I should have mentioned - The Order of Things (Les Mots et Les Choses) by Michel Foucault.)
If philosophy is the drive to understand the human condition, I don't think any philosopher can or should ignore the Bible. Athens, Rome and Jerusalem are where the Western mind was born it has been said. And there is nothing to stop you approaching the Bible as it were hermeneutically, ie. in the same way you might treat the Greek Myths. I find it fascinating myself - from the "ex nihilo" of Genesis, through the "de profundis" of the Psalms, to Job's "Why?!", not to mention the Christian New Testament - and I think it will be read (by philosophers) long after many books in "The Philosophy Section" have been forgotten.
But the bible itself isn't a good philosophy book. Meta-bible discussions, including those by Christian scholars, might form a good corpus of philosophy, however.

Well I just interpret "philosophy" more broadly. Before we can act, and indeed before we can think, we must somehow plant our feet - we can't stand "nowhere" in a sense. And philosophy is just the search for a good place to stand, a "will to locate oneself" perhaps. And if we habitually stand in the same place, we're religious! We can no more be beyond (super) philosophy than we can be beyond (super) religion than we can be beyond (super) man. In this sense, the authors of the books of the bible are philosophers like the rest of us. If it's dissimilar in style to Plato, Aristotle and so on, there you go. So when you say it isn't a good philosophy book, to my mind you're just saying you don't like the philosophy it evinces, which of course is your prerogative.
While the Bible as a whole isn't a philosophy book, it does contain a few. Books like the Proverbs of Solomon, Ecclesiastes, the Book of Job, etc. are what we could call "practical philosophy."
