Esther 9:16-19

Meanwhile in the rest of the king’s provinces, the Jews had organized and defended themselves, freeing themselves from oppression. On the thirteenth day of the month of Adar, they killed seventy-five thousand of those who hated them but did not take any plunder. The next day, the fourteenth, they took it easy and celebrated with much food and laughter. But in Susa, since the Jews had banded together on both the thirteenth and fourteenth days, they made the fifteenth their holiday for laughing and feasting. (This accounts for why Jews living out in the country in the rural villages remember the fourteenth day of Adar for celebration, their day for parties and the exchange of gifts.) * * *
