Prophetic works were also of particular interest to the Persian-era authors, with some works being composed at this time (the last ten chapters of Isaiah and the books of Haggai, Zechariah, Malachi and perhaps Joel) and the older prophets edited and reinterpreted. The corpus of Wisdom books saw the composition of Job, parts of Proverbs, and possibly Ecclesiastes, while the book of Psalms was possibly given its modern shape and division into five parts at this time (although the collection continued to be revised and expanded well into Hellenistic and even Roman times).
