Esther 9:17–19, 22
This was done on the thirteenth day of the month of Adar, and on the fourteenth day they rested, making it a day of feasting and joy. / The Jews in Susa, however, had assembled on the thirteenth and the fourteenth days of the month. So they rested on the fifteenth day, making it a day of feasting and joy. / This is why the rural Jews, who live in the villages, observe the fourteenth day of the month of Adar as a day of joy and feasting. It is a holiday for sending gifts to one another.
