Creating the Canon
The process and the product of the canonization of the Bible became the basis for a varied tradition of interpretation.

The term "canon" refers to the closed corpus of biblical literature regarded as divinely inspired. The Hebrew biblical canon represents a long process of selection, as testified to by the Bible itself, which lists some twenty‑two books that have been lost to us, no doubt, among other reasons, because they were not included in the canon. Books were only included if they were regarded as holy, that is, divinely inspired.
The Hebrew Bible is divided into three parts, Torah (Pentateuch), Prophets, and Writings. This division is not strictly one of content; it derives from the canonization process in that the three parts were closed at separate times.
"The Torah of Moses" was already the name for the first part in the various postexilic books. We will not attempt here to deal with the complex questions regarding the history and authorship of the Torah. Suffice it to say that a unified, canonized Torah was available to Ezra for the public reading which took place in approximately 444 B.C.E. Further, the various legal interpretations (midrashim) found in the books of Ezra and Nehemiah are themselves a result of the issues raised by a Torah in which there are apparent contradictions and repetitions. It can therefore be stated unquestionably that the canonization of the Torah was completed by the time of Ezra and Nehemiah.
Later rabbinic tradition asserts that prophecy ceased with the conquest of Alexander the Great in 332 B.C. E. In effect, this meant that books composed thereafter were not to be included in the prophetic canon, the second of the Hebrew Bible's three parts. This view can be substantiated by the absence of later debate about the canonicity of the prophets, the lack of Greek words in the prophetic books, and the inclusion of Daniel and Chronicles in the Writings rather than in the Prophets.It must be the case, therefore, that the Prophets were canonized late in the Persian period, probably by the start of the fourth century
The Writings are a diverse collection. Some of the books included in this corpus are earlier than the canonization of the Prophets and were placed in the Writings because of their literary form or because they were regarded as having a lesser degree of divine inspiration. Other books appear in this collection because they were authored after the canon of the Prophets was closed. As already mentioned, this was the case with Daniel and Chronicles. Song of Songs and Ecclesiastes are regarded by some scholars as of Hellenistic origin, but rabbinic tradition attributes them to Solomon. Daniel is widely regarded by modern scholars as having been written in the Hellenistic period. There is no evidence at all for the oft‑repeated view that the Scriptures were formally canonized at Yavneh.
