Psalms 139:19

¹⁷ How precious to me are Your thoughts, O God, how vast is their sum!

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

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

²⁰ 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?

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