Esther 9:20

18But the Jews who were in Susa assembled together on the thirteenth and on the fourteenth days of the month; and on the fifteenth day of that month, they rested, and made it a day of feasting and gladness.

19Therefore the Jews of the villages, who live in the unwalled towns, make the fourteenth day of the month Adar a day of gladness and feasting, a holiday, and a day of sending presents of food to one another.

20Mordecai wrote these things, and sent letters to all the Jews who were in all the provinces of the King Ahasuerus, both near and far,

21to enjoin them that they should keep the fourteenth and fifteenth days of the month Adar yearly,

22as the days in which the Jews had rest from their enemies, and the month which was turned to them from sorrow to gladness, and from mourning into a holiday; that they should make them days of feasting and gladness, and of sending presents of food to one another, and gifts to the needy.
