Esther 9:17-19

17This was on the thirteenth day of the month of Adar. On the fourteenth they rested and made it a day of feasting and celebration.

18But the Jews in Susa had assembled on the thirteenth and fourteenth. They rested on the fifteenth and made it a day of feasting and celebration.

19That is why the Jews who live in the villages and in the unwalled towns make the fourteenth day of the month of Adar a holiday for feasting and celebration. They also send gifts of food to one another.
