'Discouragement' in the Bible

Moses told this to the Israelites, but they did not listen to him because of their discouragement and hard labor.

to strengthen those who mourn in Zion, by giving them a turban, instead of ashes, oil symbolizing joy, instead of mourning, a garment symbolizing praise, instead of discouragement. They will be called oaks of righteousness, trees planted by the Lord to reveal his splendor.
