Esther 9:17-19

This was on the thirteenth day of the month of Adar. And on the fourteenth of the month they rested and made it a day of feasting and gladness. But the Jews who were at Shushan assembled together on the thirteenth day, as well as on the fourteenth; and on the fifteenth of the month they rested, and made it a day of feasting and gladness. Therefore the Jews of the villages who dwelt in the unwalled towns celebrated the fourteenth day of the month of Adar with gladness and feasting, as a holiday, and for sending presents to one another.
