Esther 9:17-19

17This was doneon the thirteenth day of the month Adar; and on the fourteenth day of the same they rested, and made it a day of feasting and gladness. 18But the Jews that were in Shushan assembled together on the thirteenth day thereof, and on the fourteenth thereof; and on the fifteenth day of the same they rested, and made it a day of feasting and gladness. 19Therefore do the Jews of the villages, that dwell in the unwalled towns, make the fourteenth day of the month Adar a day of gladness and feasting, and a good day, and of sending portions one to another.
