Psalms 139:20

18 If I were to count them, they would outnumber the grains of sand; and when I awake, I am still with You.

19 O God, that You would slay the wicked— away from me, you bloodthirsty men—

who speak of You deceitfully; Your enemies take Your name in vain.

21 Do I not hate those who hate You, O LORD, and detest those who rise against You?

22 I hate them with perfect hatred; I count them as my enemies.

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