'Mourning' in the Bible

Throughout each and every province where the king's edict and law were announced there was considerable mourning among the Jews, along with fasting, weeping, and sorrow. Sackcloth and ashes were characteristic of many.

as the time when the Jews gave themselves rest from their enemies -- the month when their trouble was turned to happiness and their mourning to a holiday. These were to be days of banqueting, happiness, sending gifts to one another, and providing for the poor.
