Esther 9:29-31

Then Esther the queen, the daughter of Abihail, and Mordecai the Jew, wrote with all authority, to confirm this second letter of Purim. And he sent the letters unto all the Jews, to the hundred twenty and seven provinces of the kingdom of Ahasuerus, with words of peace and truth, to confirm these days of Purim in their times appointed, according as Mordecai the Jew and Esther the queen had enjoined them, and as they had decreed for themselves and for their seed, the matters of the fastings and their cry.
