“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.”
King James Version (KJV)
61:3 Ashes - By ashes understand whatever is proper for days of mourning, as by beauty whatever may become times of rejoicing. Oil of joy - He calls it oil of joy in allusion to those anointings they were wont to use in times of joy, gladness for heaviness; and it is called a garment in allusion to their festival ornaments, for they had garments appropriated to their conditions, some suitable to times of rejoicing, and some to times of mourning. Called - That they may be so. Trees - That they shall be firm, solid, and well rooted, being by faith engrafted into Christ, and bringing forth fruit suitable to the soil wherein they are planted.
