the Pentateuch itself, which was essentially complete before the Exile, though some editing clearly went on after the Return. This is the basic body of written Jewish law, on which all else rests. Then come the books of the prophets, the psalms and wisdom literature, canonization of which was completed, as we have seen, under Rabbi Johanan ben Zakkai, between 70 and 132 AD. To this were added various non-canonical works essential to the study of Jewish religion and history: the Greek translation of the Bible, or Septuagint; the works of Josephus; the Apocrypha and various papyri.
