Esther 9:31-32

New Century Version

³¹ He wrote to set up these days of Purim at the chosen times. Mordecai the Jew and Queen Esther had sent out the order for the Jewish people, just as they had set up things for themselves and their descendants: On these two days the people should fast and cry loudly. ³² Esther’s letter set up the rules for Purim, and they were written down in the records.
