LEV465 The ideal man, says the Psalmist (xv. 3. Called the "Gentleman's Psalm") is one who "hath no slander upon his tongue", lest he causeth thereby a shedding of blood." Nor is the actual doing or speaking of evil needed to constitute a wrong. Often a look or a smile is enough. A sudden silence is, at times, more eloquent than speech; as if one should say "I could a tale unfold, if I so wished". Such insinuation is called by the Rabbis "the fine dust of evil speaking" (abak leshon hara). God hates him who says one thing with his mouth, while he thinks another in his heart (Pes. 113b). The Talmud attaches much importance to honesty in all things, especially in commerce and industry. Jerusalem was destroyed when honest men ceased to be therein (Shabb. 119b).
