'Failing' in the Bible

Among those nations you will find no peace (rest), and there will be no resting place for the sole of your foot; but there the Lord will give you a trembling heart, failing eyes, and a despairing soul.

Then I will not be ashamedWhen I look [with respect] to all Your commandments [as my guide].

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.
