The wise of heart is called discerning,
    and sweetness of speech increases persuasiveness.
  Good sense is a fountain of life to him who has it,
    but the instruction of fools is folly.
  The heart of the wise makes his speech judicious
    and adds persuasiveness to his lips.
  Gracious words are like a honeycomb,
    sweetness to the soul and health to the body.
  There is a way that seems right to a man,
    but its end is the way to death.
  A worker’s appetite works for him;
    his mouth urges him on.
  A worthless man plots evil,
    and his speech is like a scorching fire.
  A dishonest man spreads strife,
    and a whisperer separates close friends.
  A man of violence entices his neighbor
    and leads him in a way that is not good.
