Tehillim 64:3-5

Orthodox Jewish Bible

^3 (4) Who whet their tongue like a cherev, and aim their khitzim (arrows), even davar mar (bitter words);

^4 (5) That they may shoot in secret at the tam (innoent); pitom (suddenly) do they shoot at him, and fear not.

^5 (6) They encourage themselves in a davar rah (an evil plan); they speak in order to set mokshim (snares, hidden traps); they say, Who shall see them?
