'Mourning' in the Bible

In every province [each] place where the king's edict and his law came, there [was] great mourning for the Jews with fasting, crying, wailing, [and] sackcloth; and ashes were spread out as a bed for them.

as the day that the Jews {found relief} from their enemies, and the month which changed for them from sorrow to joy, and from a mourning ceremony to a {festive day}; to make them days of feasting and joy, and giving gifts to each other and to the poor.
