Purim is distinctly a Jewish festival. Yet it gives us a wonderful picture of the Messiah our deliverer.
This 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 gladness… the Jews established and accepted a custom for themselves and for their seed and for all those who joined themselves to them, so that celebrating these two days according to what was written down and according to their fixed time from year to year would not pass away. So these days were to be remembered and celebrated throughout every generation, every family, every province and every city.
(Esther 9:17,27-28 LSB)
