Esther 9:18 - 9:19
18 But the Jews who were in Susa assembled on the thirteenth and the fourteenth of the same month, and they rested on the fifteenth day and made it a day of feasting and gladness. 19 Therefore the Jews of the rural areas, who live in the rural towns, make the fourteenth day of the month Adar a holiday for gladness and feasting and sending portions of food to one another.
