Esther 9:17-19

17This happened on the thirteenth day of the month of Adar, and on the fourteenth they rested and made it a day of feasting and joy.

18The Jews in Susa, however, had assembled on the thirteenth and fourteenth, and then on the fifteenth they rested and made it a day of feasting and joy.

19That is why rural Jews—those living in villages—observe the fourteenth of the month of Adar as a day of joy and feasting, a day for giving presents to each other.
