Book of Esther in Wikipedia
The Book of Esther is one of the books of the Hebrew Bible.
The Book of Esther or the Megillah is the basis for the Jewish
celebration of Purim. Its full text is read aloud twice during
the celebration, in the evening and again the following
morning. The Biblical Book of Esther is set in the third year
of Ahasuerus, a king of Persia. The name Ahasuerus is
equivalent to Xerxes, both deriving from the Persian
Khashayarsha, thus Ahasuerus is usually identified as Xerxes I
(486-465 BCE), though Ahasuerus is identified as Artaxerxes in
the later Greek version of Esther (as well as by Josephus, the
Jewish commentary Esther Rabbah, the Ethiopic translation and
the Christian theologian Bar-Hebraeus who identified him more
precisely as Artaxerxes II ). The Book of Esther tells a
story of palace intrigue and genocide thwarted by a Jewish
queen of Persia...
