Due to the ancient tradition that the same writer composed both parts of the book (chapters 1-6 and 7-10), many scholars believe Ezra produced all of it.5A passage in the Talmud credits Ezra with the authorship of Ezra-Nehemiah and Chronicles.6Ezra speaks in the first person in Ezra 7:28-8:34 and in chapter 9. This may suggest that he drew from a source such as the so-called "Ezra Memoirs"that recorded Ezra's personal recollections in the first person.7
Another popular view is that Ezra and Nehemiah each wrote the books that bear their names.8A third view is that the joint book was a compilation that a "chronicler"made long after the events recorded took place.9
As a scribe (7:21), Ezra had the qualifications needed to write this book. He was a general contemporary of Nehemiah (Neh. 8:1-9; 12:36). Another reference in the Talmud claimed that Ezra was a disciple of Baruch, Jeremiah's scribe.10
The last historical reference in the book is in 4:21-23. In view of other chronological references in the book this event must have occurred about 446 B.C. Therefore Ezra could have written the book about 446 B.C. or shortly after that.
"Regardless of one's view of the authorship of Ezra-Nehemiah and its relationship to Chronicles, the theological viewpoint of the whole collection is essentially the same. The message is addressed to the postexilic community of Jews who wonder if there is any hope of political and religious restoration. Its central thrust is that there indeed is hope but that hope must be incarnated in the rebuilding of the Temple, the cultus, and the priesthood. Only as the remnant people became the theocratic nation, founded on and faithful to the covenant Yahweh made with their fathers, could they revive the Davidic house and anticipate the resumption of their mediatorial role among the nations of the earth. Ezra and Nehemiah are therefore burdened to clarify (1) the Person and works of God, (2) Israel's own identity and function as a covenant people, and (3) the nature of that covenant in postexilic times."11
