To grant [consolation and joy] to those who mourn in Zion–to give them an ornament (a garland or diadem) of beauty instead of ashes, the oil of joy instead of mourning, the garment [expressive] of praise instead of a heavy, burdened, and failing spirit–that they may be called oaks of righteousness [lofty, strong, and magnificent, distinguished for uprightness, justice, and right standing with God], the planting of the Lord, that He may be glorified.
