The names of the books of the Bible

Growing up I remember memorizing the names of the books of the Bible but I never thought about the name itself. When you read alot of other regular books, the name of the chapter gives you a clue as to how the chapter unfolds. I was thinking about it today and as we have gone thru almost 5 books, Genisis (the begining), Exodus (the leaving Egypt), Leviticus (maybe because we are to think more of the Levites?), Numbers (the census) and Deuteronomy (the second law, rough dictionary description), it is just an interseting subject note.
