Psalms 140:7

5 The proud have hid a snare for me, and cords; they have spread a net by the wayside; they have set gins for me. Selah.

6 I said unto the LORD, Thou art my God: hear the voice of my supplications, O LORD.

O GOD the Lord, the strength of my salvation, thou hast covered my head in the day of battle.

8 Grant not, O LORD, the desires of the wicked: further not his wicked device; lest they exalt themselves. Selah.

9 As for the head of those that compass me about, let the mischief of their own lips cover them.

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