'Mourning' in the Bible

And in that day did the Lord Jehovah of hosts call to weeping, and to mourning, and to baldness, and to girding with sackcloth;

Thy sun shall no more go down, neither shall thy moon withdraw itself; for Jehovah shall be thine everlasting light, and the days of thy mourning shall be ended.

to appoint unto them that mourn in Zion, that beauty should be given unto them instead of ashes, the oil of joy instead of mourning, the garment of praise instead of the spirit of heaviness: that they might be called terebinths of righteousness, the planting of Jehovah, that he may be glorified.
