the Greek words for "second canon"), books not included in the Jewish canon. These books are estimated to have been written between 200 BCE and 50 CE. Among them are the first two books of Maccabees; Tobit; Judith; the Wisdom of Solomon; Sirach; Baruch (including the Letter of Jeremiah), and additions to Esther and Daniel. The Septuagint version of some books, such as Daniel and Esther, are longer than those in the Masoretic Text, which were affirmed as canonical in Rabbinic Judaism. The Septuagint Book of Jeremiah is shorter than the Masoretic Text. The Psalms of Solomon, 3 Maccabees, 4 Maccabees, the Letter of Jeremiah, the Book of Odes, the Prayer of Manasseh and Psalm 151 are included in some copies of the Septuagint. While the Septuagint appears to have been widely accepted by Jews of the Second Temple period, it has been largely rejected as scriptural by mainstream Rabbinic Judaism since late antiquity for several reasons. First, the Septuagint differs from the Hebrew source texts in many cases (particularly in the Book of Job). Second, the translations appear at times to demonstrate an ignorance of Hebrew idiomatic usage. A particularly noteworthy example of this phenomenon is found in Isaiah 7:14, in which the Hebrew word (‘almāh, which translates into English as "young woman") is translated into the Koine Greek as (parthenos, which translates into English as "virgin"). Finally, the rabbis also wanted to distinguish their tradition from the emerging tradition of Christianity, which relied heavily on the Septuagint. The Septuagint became synonymous with the Greek Old Testament, a Christian canon incorporating the books of the Hebrew canon with additional texts. Although the Catholic Church and the Eastern Orthodox Church include most of the books in the Septuagint in their canons, Protestant churches usually do not. After the Reformation, many Protestant Bibles began to follow the Jewish canon and exclude the additional texts (which came to be called the Apocrypha) as noncanonical. The Apocrypha are included under a separate heading in the King James Version of the Bible. Final form All the books in Western Old Testament biblical canons are found in the Septuagint, although the order does not always coincide with the Western book order. The Septuagint order is evident in the earliest Christian Bibles, which were written during the fourth century. Some books which are set apart in the Masoretic Text are grouped together.
