GEN238 [Targum Onkeles [this verse] translates “living being” as “a speaking being.”]  What Jack London said about writing is equally applicable to speaking: Pretend each word you use costs a thousand dollars.  It was the abuse rather than the use of speech that often advised silence.  As Orhot Zaddikim observes, “Humans were created with two eyes, two ears, and two nostrils, but only with one mouth because one should speak less.”  HTBAJ 195
