Esther 9:29–32
So Queen Esther daughter of Abihail, along with Mordecai the Jew, wrote with full authority to confirm this second letter concerning Purim. / And Mordecai sent letters with words of peace and truth to all the Jews in the 127 provinces of the kingdom of Xerxes, / in order to confirm these days of Purim at their appointed time, just as Mordecai the Jew and Queen Esther had established them and had committed themselves and their descendants to the times of fasting and lamentation.
