Psalms 64:4-8

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.

So they shall make their own tongue to fall upon themselves: all that see them shall flee away.
