What are two versions of the old testament Bible?

Versions of the Old Testament

There are two versions of the Old Testament which are the Alexandria Version and the Jewish Canon.

To understand this one has to understand the origin. Alexandria is located in the country of Egypt, on the southern coast of the Mediterranean. The Alexandria version of the old testament derives its name from the city of Alexandria (in Egypt), where it resided for a number of years before it was brought by the Eastern Orthodox Patriarch Cyril Lucaris from Alexandria to Constantinople (modern day Istanbul in Turkey). Then it was given to Charles I of England in the 17th century.

The Hebrew Bible or Tanakh also known in Hebrew as Miqra is the canonical collection of Hebrew scriptures, including the Torah (The Law), the Nevi’im (Prophetet), and the Ketuvim (writings). The Jewish and Christian Bibles do not contain the same books and they are not arranged in the same order. There is a different “canon,” a different listing of the biblical books in the collections that Jews call Tanakh and Christians call the Old Testament. The Torah is seen as the most important part of the Jewish Bible, The Torah has central importance in Jewish life, ritual and belief. The Jewish old testament contains 24 books however it is quite similar to the 39 books in the protestant old testament bible. Among the 24 books, there is a single book that contains (12) twelve prophetic writings and it is referred as (Dodecapropheton), and also 4 books aside the 12 prophetic writings (which is counted as 1) are counted individually in the Jewish bible. These 4 however makes another 8 books in the protestant bible.

so mathematically,

24-1prophetic writing which becomes 12 =23 books left

23- 4 individual books which becomes 8 = 19 

therefore 12+8+19 = the 39 books of the protestant church bible (the bible we use in churches that broke away from catholic and  mordern churches)
