Esther, Book of - The authorship of this book is unknown. It must have been obviously written after the death of Ahasuerus (the Xerxes of the Greeks), which took place B.C. 465. The minute and particular account also given of many historical details makes it probable that the writer was contemporary with Mordecai and Esther. Hence we may conclude that the book was written probably about B.C. 444-434, and that the author was one of the Jews of the dispersion.
And all the acts of his power and of his might, and the declaration of the greatness of Mordecai, whereunto the king advanced him, are they not written in the book of the chronicles of the kings of Media and Persia?
