Psalms 64:2-6

Hide me from the secret counsel of the wicked; from the insurrection of the workers of iniquity:

Who whet their tongue like a sword, and bend their bows to shoot their arrows, even bitter words:

That they may shoot in secret at the perfect: suddenly do they shoot at him, and fear not.

They encourage themselves in an evil matter: they commune of laying snares privily; they say, Who shall see them?

They search out iniquities; they accomplish a diligent search: both the inward thought of every one of them, and the heart, is deep.
