'Mourner's' in the Bible

"Grieve like a virgin, who, dressed in her mourner's clothes, cries out in memory of the man she was going to marry.

"Put on your mourning clothes, you priests; and cry aloud, you ministering servants at the altar! Come! Stay the night in mourner's clothes, you ministers of my God, because the grain offering and the wine offering is held back from the Temple of your God.
