Psalms 64:4-6

MLV(i) 4 that they may shoot in secret places at a blameless man. Suddenly do they shoot at him and do not fear.
5 They encourage themselves in an evil purpose. They speak of laying snares secretly. They say, Who will see them?
6 They search out iniquities, saying, We have accomplished a diligent search. And the inward part of man and the heart are deep.
