Christine Hayes contrasts the Book of Esther with apocalyptic writings, the Book of Daniel in particular: both Esther and Daniel depict an existential threat to the Jewish people, but while Daniel commands the Jews to wait faithfully for God to resolve the crisis, in Esther the crisis is resolved entirely through human action and national solidarity. God, in fact, is not mentioned, Esther is portrayed as assimilated to Persian culture, and Jewish identity in the book is an ethnic category rather than a religious one.
