Esther 9:18-22

(The Jews at Susa killed their enemies on March 7 and again on March 8, then rested on March 9, making that their day of feasting and gladness.) So to this day, rural Jews living in remote villages celebrate an annual festival and holiday on the appointed day in late winter, when they rejoice and send gifts of food to each other. Mordecai recorded these events and sent letters to the Jews near and far, throughout all the provinces of King Xerxes, calling on them to celebrate an annual festival on these two days. He told them to celebrate these days with feasting and gladness and by giving gifts of food to each other and presents to the poor. This would commemorate a time when the Jews gained relief from their enemies, when their sorrow was turned into gladness and their mourning into joy.
