The days the Jews were celebrating were called Purim. Purim comes from the word "pur". "Pur" means "lot." Now the Jews celebrate those two days every year. They do it because of everything that was written in Mordecai's letter. They also do it because of what they had seen and what had happened to them.
So they established it as a regular practice. They decided they would always observe those two days of the year. They would celebrate in the required way. And they would celebrate at the appointed time. They and their children after them and everyone who joined them would always observe those days.
The days should be remembered and celebrated. They should be remembered by every family for all time to come. They should be celebrated in every territory and in every city. The Jews should never stop celebrating the days of Purim. Their children after them should always remember those days.
So Queen Esther, the daughter of Abihail, wrote a second letter. She wrote it together with the Jew Mordecai. They wanted to give their full authority to this second letter about Purim.
Mordecai sent letters to all of the Jews in the 127 territories of the kingdom of Xerxes. The letters had messages of kindness and hope in them.
The letters established the days of Purim at their appointed times. They spoke about what the Jew Mordecai and Queen Esther had ordered the people to do. Everything should be done in keeping with the directions the Jews had set up for themselves and their children after them. The directions applied to their times of fasting and sadness.
Esther's order established the rules about Purim. It was written down in the records.
