Esther 9:29-32

29Then Queen Esther the daughter of Abihail, and also Mordecai the Jew, wrote with full authority to confirm this second letter of Purim.

30He sent letters to all the Jews in the 127 provinces of the kingdom of Ahasuerus, with words of shalom and truth,

31to establish these days of Purim at their designated times, just as Mordecai the Jew and Queen Esther had decreed for them and just as they had established for themselves and their descendants, matters regarding their times of fasting and lamentations.

32Esther’s command confirmed these regulations about Purim and it was written into the records.
