Ezra and Chronicles were likely written by the same author, and the Chronicler probably wrote around 350 B.C. (For discussion of the authorship of Ezra and Chronicles, see Menahem Haran, “Explaining the Identical Lines at the End of Chronicles and the Beginning of Ezra,” Bible Review, Fall 1986, and Hugh G. M. Williamson, “Did the Author of Chronicles Also Write the Books of Ezra and Nehemiah?” Bible Review, Spring 1987.)
