To appoint unto them that mourn in Zion, to give unto them beauty for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness; that they might be called trees of righteousness, the planting of the LORD, that he might be glorified.
To give hope to those who are sad in Zion, replacing their sadness with beauty, swapping their sorrow with joy, and exchanging their heavy hearts for praise; so they can be called righteous trees, planted by the LORD, bringing him glory.
