To grant to those who mourn in Zion the following:To give them a turban instead of dust [on their heads, a sign of mourning],The oil of joy instead of mourning,The garment [expressive] of praise instead of a disheartened spirit.So they will be called the trees of righteousness [strong and magnificent, distinguished for integrity, justice, and right standing with God],The planting of the Lord, that He may be glorified.
