Esther 9:17-19

¹⁷This was done on the thirteenth day of the month Adar, and on the fourteenth day they rested and made it a day of feasting and rejoicing.

¹⁸But 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 rejoicing. ¹⁹Therefore the Jews of the rural areas, who live in the rural towns, make the fourteenth day of the month Adar a holiday for rejoicing and feasting and sending portions of food to one another.
