The order of the books in the Pentateuch and "Former Prophets" (Joshua-Kings) is fixed by the historical sequence, and therefore constant; among the "Latter Prophets" Jeremiah was sometimes put first, immediately following the end of Kings, with which it was so closely connected. In the third group there was no such obvious principle of arrangement, and consequently there were different opinions about the proper order; that which is given above follows the oldest deliverance on the subject, and puts them in what the rabbis doubtless supposed to be a chronological series. So long as the books were written on separate rolls of papyrus, the question of order was theoretical rather than practical; and even when manuscripts were written in codex form (on folded leaves stitched together like our books), no uniformity was attained. At the beginning of the Christian era, lessons from the Law were regularly read in the synagogues on the sabbath (the Pentateuch being so divided that it was read through consecutively once in three years), and a second lesson was chosen from the Prophets. The title of these books to be regarded as Sacred Scripture was thus established by long-standing liturgical use, and was, indeed, beyond question. Nor was there any question about the inspiration of most of the books in the third group, the "Scriptures." There was a controversy, however, over Ecclesiastes and the Song of Songs; some teachers of the strictest school denied that either of them was inspired, while others accepted only one of them. The question was voted on in a council of rabbis held at Jamnia about the beginning of the second century of our era, and the majority decided for the inspiration of both books. There were also, even down to the third century, Jewish scholars who did not acknowledge Esther as Sacred Scripture. On the other hand, some were inclined to include among the Sacred Books the Proverbs of Ben Sira, which stand in the English Bible among the Apocrypha under the title Ecclesiasticus.
