'Sackcloth and Ashes' in the Bible

Now when Mordecai became aware of all that had been done, he tore his garments and put on sackcloth and ashes. He went out into the city, crying out in a loud and bitter voice.

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.
