Esther 9:19

The other Jews who were in the king’s provinces gathered themselves together, defended their lives, had rest from their enemies, and killed seventy-five thousand of those who hated them; but they didn’t lay their hand on the plunder.

This was done on the thirteenth day of the month Adar; and on the fourteenth day of that month they rested and made it a day of feasting and gladness.

But the Jews who were in Susa assembled together on the thirteenth and on the fourteenth days of the month; and on the fifteenth day of that month, they rested, and made it a day of feasting and gladness.

Mordecai wrote these things, and sent letters to all the Jews who were in all the provinces of the King Ahasuerus, both near and far,

to enjoin them that they should keep the fourteenth and fifteenth days of the month Adar yearly,

as the days in which the Jews had rest from their enemies, and the month which was turned to them from sorrow to gladness, and from mourning into a holiday; that they should make them days of feasting and gladness, and of sending presents of food to one another, and gifts to the needy.
