Esther 9:20-22

Mordecai wrote these things, and sent letters to all the Jews who were in all the provinces of the King Ahasuerus, both near and far, to enjoin them that they should keep the fourteenth and fifteenth days of the month Adar yearly, as 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.
