The term 'Celebration of Deliverance' refers to the Jewish holiday of Purim, which is celebrated annually on the 14th day of the Hebrew month of Adar. The holiday commemorates the deliverance of the Jewish people from a plot to annihilate them in the ancient Persian Empire as recorded in the Biblical book of Esther. During the celebration, Jews read the Megillah (the Scroll of Esther), give gifts of food and money to the poor, and enjoy a festive meal.
