When Was the Book of Proverbs Written?

The authorship of the book gives parameters to its date. Given the conclusion above regarding chaps. 1–24, this section would be dated to the time of Solomon (around 950 BC). The compilation of chaps. 25–29, as indicated in the text itself, would be dated at the time of Hezekiah (716–687 BC). What about chaps. 30–31? There is no external or internal evidence to date this material. Consequently, no firm date can be affixed to the final editing of Proverbs, though it is possible that it was as early as the time of Hezekiah.
