Esther 9:31-32

New Living Translation

³¹ These letters established the Festival of Purim—an annual celebration of these days at the appointed time, decreed by both Mordecai the Jew and Queen Esther. (The people decided to observe this festival, just as they had decided for themselves and their descendants to establish the times of fasting and mourning.) ³² So the command of Esther confirmed the practices of Purim, and it was all written down in the records.
