 Lester Grabbe (2003), based on various factors including the type of Aramaic used in the youngest sections and the ignorance of Ezra–Nehemiah as a single book displayed by other Hellenistic Jewish writers, suggests that the two texts were combined, with some final editing, in the Ptolemaic period, c. 300c.200 BC.The order of the two figures, Ezra and Nehemiah, is perhaps the most debated issue regarding the book.
