Psalms 64:3-6

³They have sharpened their tongues like swords; they have aimed their arrows, bitter words,

⁴so that they may shoot from secret places at someone who is innocent; suddenly they shoot at him and fear nothing.

⁵They encourage themselves in an evil plan; they consult privately together in order to set traps; they say, “Who will see us?”

⁶They invent sinful plans; “We have finished,” they say, “a careful plan.” The inner thoughts and hearts of man are deep.
