Psalms 64:3-6

64:3 They sharpen their tongues like a sword;

they aim their arrow, a slanderous charge,

64:4 in order to shoot down the innocent in secluded places.

They shoot at him suddenly and are unafraid of retaliation.

64:5 They encourage one another to carry out their evil deed.

They plan how to hide snares,

and boast, “Who will see them?”

64:6 They devise unjust schemes;

they disguise a well-conceived plot.

Man’s inner thoughts cannot be discovered.
