Esther 4:1

1 When Mordecai learned of all that had been done, he tore his clothes, put on sackcloth and ashes, and went out into the city, wailing loudly and bitterly.

28 These days should be remembered and observed in every generation by every family, and in every province and in every city. And these days of Purim should never fail to be celebrated by the Jews—nor should the memory of these days die out among their descendants.
