Psalms 64:3-7

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.

But God shall shoot at them with an arrow; suddenly shall they be wounded.
