Psalms 139:20

¹⁸ If I should count them, they are more in number than the sand: when I awake, I am still with thee.

¹⁹ Surely thou wilt slay the wicked, O God: depart from me therefore, ye bloody men.

For they speak against thee wickedly, and thine enemies take thy name in vain.

²¹ Do not I hate them, O LORD, that hate thee? and am not I grieved with those that rise up against thee?

²² I hate them with perfect hatred: I count them mine enemies.

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