'Mourners' in the Bible

Setting up on high those that are low; and mourners are exalted to prosperity.

I chose their way, and sat as chief, and dwelt as a king in the army, as one that comforteth mourners.

they are also afraid of what is high, and terrors are in the way, and the almond is despised, and the grasshopper is a burden, and the caper-berry is without effect; (for man goeth to his age-long home, and the mourners go about the streets;)

They shall pour out no offerings of wine to Jehovah, neither shall their sacrifices be pleasing unto him: they shall be unto them as the bread of mourners; all that eat thereof shall be defiled: for their bread shall be for themselves; it shall not come into the house of Jehovah.
