First you have to remember that chapters and verses were added to the Bible later, and by Catholic printers no less in order to make it easier to find passages. Before that all the Books of the Bible were just written down the way a letter would be written.

When the first (Chrisitan) Bibles were transcribed they were all written in unical (All capital letters) in Greek. They were hand written and did not include punctuation marks, all the letters basically ran together, so one had to be literate and know the subject to read a book.

Jewish sects up until around 600 AD were not united in how many books were considered Biblical, nor the order abreviating the Ten Commandments. Each group broke them down differently, Protestants chose a manner that they liked, Catholics stuck with the breakdown that had been kept by the early Church.
