Proverbs 26: A Message to Wicked Politicians

23  Fervent lips with a wicked heart
      Are like earthenware covered with silver dross.
24  He who hates, disguises it with his lips,
      And lays up deceit within himself;
25  When he speaks kindly, do not believe him,
      For there are seven abominations in his heart;
26  Though his hatred is covered by deceit,
      His wickedness will be revealed before the assembly.
