'Mourning' in the Bible

And I have sent distress to Ariel, And it hath been lamentation and mourning, And it hath been to me as Ariel.

His ways I have seen, and I heal him, yea, I lead him, And recompense comforts to him and to his mourning ones.

Is it not to deal to the hungry thy bread, And the mourning poor bring home, That thou seest the naked and cover him, And from thine own flesh hide not thyself?

Thy sun goeth no more in, And thy moon is not removed, For Jehovah becometh to thee a light age-during. And the days of thy mourning have been completed.

To appoint to mourners in Zion, To give to them beauty instead of ashes, The oil of joy instead of mourning, A covering of praise for a spirit of weakness, And He is calling to them, 'Trees of righteousness, The planting of Jehovah -- to be beautified.'

Rejoice ye with Jerusalem, And be glad in her, all ye loving her, Rejoice ye with her for joy, All ye are mourning for her,
