The Book of Ezra is a book of the Hebrew Bible which formerly included the Book of Nehemiah in a single book, commonly distinguished in scholarship as Ezra–Nehemiah. The two became separated with the first printed rabbinic bibles of the early 16th century, following late medieval Latin Christian tradition. Composed in Hebrew and Aramaic, its subject is the Return to Zion following the close of the Babylonian captivity. Together with the Book of Nehemiah, it represents the final chapter in the historical narrative of the Hebrew Bible.
