'Sackcloth and Ashes' in the Bible

And Mordecai knew all that was done, and Mordecai will rend his garments, and put on sackcloth and ashes, and he will go forth into the city, and he will cry out a great and bitter cry;

And in every province and province the place where the word of the king and his edict coming, great mourning to the Jews, and fasting and weeping and wailing; sackcloth and ashes will be spread to many.
