The Day of fasting instituted by Queen Esther in ancient Persia to arouse the Jewish People to Repentance. This was to avert the evil decree to implement the genocidal plan of Haman to kill all the Jews on one day, the thirteenth of Adar. Fortunately, the Teshuvah was successful, and Haman’s plan was overturned upon himself, and he spent Purim swinging with his ten sons from the gallows that he had prepared for Mordechai. At the end of this Fast Day is the beginning of Purim, which begins with the Reading of Megillat Esther.
