Purim is a joyous holiday that affirms and celebrates Jewish survival and continuity throughout history. The main communal celebration involves a public reading—usually in the synagogue—of the Book of Esther (M'gillat Esther), which tells the story of the holiday: Under the rule of King Ahashverosh, Haman, the king's adviser, plots to exterminate all of the Jews of Persia. His plan is foiled by Queen Esther and her cousin Mordechai, who ultimately save the Jews of Persia from destruction. The reading of the m'gillah typically is a rowdy affair, punctuated by booing and noise-making when Haman's name is read aloud.
You shall further instruct the Israelites to bring you clear oil of beaten olives for lighting, for kindling lamps regularly. - Exodus 27:20
