As explained in this verse, the Jewish holiday of Purim is established to be celebrated annually on the fourteenth and fifteenth days of the month of Adar. This holiday commemorates the miraculous events described in the Book of Esther, when the Jewish people were saved from a plot to destroy them. The observance of Purim includes reading the Book of Esther, giving gifts of food to friends and neighbors, donating to the poor, and feasting in celebration of the deliverance of the Jewish people. The specific dates of the fourteenth and fifteenth days of Adar were chosen based on the events described in the Book of Esther, when the Jews defeated their enemies and were granted the right to defend themselves. By commemorating these days annually, Jews around the world remember the importance of standing up against persecution and celebrating the triumph of good over evil.
