Analysis of information sources in references of the Wikipedia article "Book of Proverbs" in English language version.
Turning to more recent research on the book of Proverbs, two main approaches have been taken. Some scholars have followed Gressmann in postulating that the different parts of the book go back to different periods and that Proverbs 1-9 and (30-)31 are the latest sections. Thus, chaps. 1-9 are situated in the Persian period, and the final redaction of the book is dated to the late Persian or Hellenistic period. Others begin with the received form of the book of Proverbs, inquiring first into the meaning of the book as a whole.
