'Mourning' in the Bible

In each and every province that the decree and law of the king reached, there was great mourning among the Jews, with fasting, weeping and wailing; and many lay on sackcloth and ashes.

Then Mordecai returned to the king’s gate. But Haman hurried to his [own] house, mourning and with his head covered [in sorrow].

because on those days the Jews rid themselves of their enemies, and as the month which was turned for them from grief to joy and from mourning into a holiday; that they should make them days of feasting and rejoicing and sending choice portions of food to one another and gifts to the poor.
