Billy Budd and The Bible?

I just finished Billy Budd, and I have a bit to say about it.  First of all I have never really been able to get into any of Melville books.  Usually when I say that people respond "oh you probably don't understand it yet"  but I keep going back to them and I realized...  I do understand them.  They are no more complicated than Shakespeare and I love Hamlet, I just don't really like them.  This is surprising to me because I like very literary books.  Regardless I was required to read Billy Budd, and throughout the book there were countless biblical metaphors and similes, the majority to the old testament male lead roles.  Billy is compared to characters like Moses and Joseph.  He is an innocent, and possibly over trusting.  I personally think he is the most like Joseph and the shipmates are his brothers, Jacobs other sons.  Claggart reminds me a bit of Laban, a less known biblical character,  I see similarities in their moral compass and arguable narcissism.  It was mentioned in class that captain Vere could be a metaphor for God, but I don't think so.  I would argue that he would be Abraham, devoted to what he was set on earth to do and perhaps there are parallels in the hanging of Billy and the near sacrifice of Issac.  Of course I am just spit-balling here, I could be completely off the mark, especially because I only have knowledge of the old testament, but it helps me to analyze the characters.
