There are two different versions of the Jewish canon of scripture; one is the Greek, which is the version used in Catholic Bibles. The other is the Hebrew, which is used for many Protestant Bibles, although more & more of them have the additional books/parts of books in a separate section.
Jews today use the shorter Hebrew canon. However, the Septuagint was in use in New Testament times, & this was/is the longer Greek version which stands behind the Latin Vulgate.
