Psalms 36:3

¹ An oracle is in my heart regarding the transgression of the wicked man: There is no fear of God before his eyes.

² For his eyes are too full of conceit to detect or hate his own sin.

The words of his mouth are wicked and deceitful; he has ceased to be wise and well-doing.

⁴ Even on his bed he plots wickedness; he sets himself on a path that is not good; he fails to reject evil.

⁵ Your loving devotion, O LORD, reaches to the heavens, Your faithfulness to the clouds.

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