The book of Ezra is counted as an historical book in our English Bibles, but in the Jewish scriptures it is among the writings.

The book was originally written in Hebrew (except Ezra l7.12-26, which is in Aramaic), but the ancient Greek translation known as the Septuagint (abbreviated LXX) is also a very important witness to the text. This book in the LXX bears the title of 2 Esdras (or Esdras B), 1 Esdras (or Esdras A) being one of the apocryphal books extant in the LXX but not in the Hebrew scriptures. Also, the books of Ezra and of Nehemiah are considered the first and second parts, respectively, of the same book both in the LXX and in the Masoretic Hebrew traditions:
