Esther 9:16-19

But the other Jews that were in the king's provinces gathered themselves together, and stood for their lives, and had rest from their enemies, and slew of their foes seventy and five thousand, but they laid not their hands on the prey, on the thirteenth day of the month Adar; and on the fourteenth day of the same rested they, and made it a day of feasting and gladness. But the Jews that were at 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. Therefore the Jews of the villages, that dwelt in the unwalled towns, made the fourteenth day of the month Adar a day of gladness and feasting, and a good day, and of sending portions one to another.
