the addition of one section; its verses are numbered differently. Just as Ezra begins with the last two verses of 2 Chronicles, 1 Esdras begins with the last two chapters; this suggests that Chronicles and Esdras may have been read as one book at sometime in the past. Ezra 4:6 includes a reference to a King Ahasuerus. Etymologically, Ahasuerus is the same as Xerxes, who reigned between Darius I and Artaxerxes I. Eighteenth-century expositor John Gill, who deemed the reference to Xerxes out of place, identified Ahasuerus with Cambyses II. Nineteenth-century commentator Adam Clarke identified him with Bardiya, who both reigned before Darius I. In 1 Esdras, the section is reorganized, leading up to the additional section, and the reference to Ahasuerus is removed. The additional section begins with a story variously known as the 'Darius contest' or 'Tale of the Three Guardsmen' which was interpolated into 1 Esdras 3:4 to 4:4. This section forms the core of 1 Esdras with Ezra 5, which together are arranged in a literary chiasm around the celebration in Jerusalem at the exiles' return. This chiastic core forms 1 Esdras into a complete literary unit, allowing it to stand independently from the book of Nehemiah. Indeed, some scholars, such as W. F. Albright and Edwin M. Yamauchi, believe that Nehemiah came back to Jerusalem before Ezra. Author and criticism The purpose of the book seems to be the presentation of the dispute among the courtiers, the 'Tale of the Three Guardsmen', to which details from the other books are added to complete the story. Since there are various discrepancies in the account, most scholars hold that the work was written by more than one author. However, some scholars believe that this work may have been the original, or at least the more authoritative; the variances that are contained in this work are so striking that more research is being conducted. Furthermore, there is disagreement as to what the original language of the work was, Greek, Aramaic, or Hebrew. Because of similarities to the vocabulary in the Book of Daniel, it is presumed by some that the authors came from Lower Egypt and some or all may have even had a hand in the translation of Daniel. Assuming this theory is correct, many scholars consider the possibility that one chronicler wrote this book. Josephus makes use of the 1 Esdras which he treats as Scripture,
