'Mourning' in the Bible

O daughter of my people, gird thee with sackcloth, and wallow thyself in ashes: make thee mourning, as for an only son, most bitter lamentation: for the spoiler shall suddenly come upon us.

Thus saith the LORD of hosts, Consider ye, and call for the mourning women, that they may come; and send for cunning women, that they may come:

For thus saith the LORD, Enter not into the house of mourning, neither go to lament nor bemoan them: for I have taken away my peace from this people, saith the LORD, even lovingkindness and mercies.

Neither shall men tear themselves for them in mourning, to comfort them for the dead; neither shall men give them the cup of consolation to drink for their father or for their mother.

Then shall the virgin rejoice in the dance, both young men and old together: for I will turn their mourning into joy, and will comfort them, and make them rejoice from their sorrow.
