Job 17:9

⁷ My eyes have grown dim with grief, and my whole body is but a shadow.

⁸ The upright are appalled at this, and the innocent are stirred against the godless.

Yet a righteous one holds to his way, and the one with clean hands grows stronger.

¹⁰ But come back and try again, all of you. For I will not find a wise man among you.

¹¹ My days have passed; my plans are broken off— even the desires of my heart.

Do read the surrounding verses too, because the context often says more than a single verse.
