Bible Books Cosine Similarity

How do the books of the KJV Bible compare to each other word for word?  Are Old Testament books more similar to other Old Testament books?  Same for the New Testament?  What about the Greek (Nestle-Aland 26th/27th edition) translation of the New Testament?

Naturally, I wrote a little perl program of the classic NLP measure to tell me: cosine-similarity.  It is not the most efficient but it works perfectly!

Here are the KJV results:

Knowing that Moses wrote the first 5 books tells me that other clusters of linked books might be by the same author, too...  However, this analysis considers the KJV translation more than it represents the "actual text" - of the original writings.
