"I have no words; my voice is my sword". (act 5 Macduff).

• In using a violent metaphor, Macduff argues that restoring Scotland's natural order requires physical force - he aims to rightfully reclaim Scotland from Macbeth's misuse of kingship.  Macduff believes that the violence Macbeth used requires the same kind of strength to set things straight and restore the disrupted divine right of kings.

  Macduff is like a classic hero seeking revenge. Despite his personal anger, he's honorable in wanting to end the chaos from Macbeth's bad kingship. He's determined to defeat Macbeth and bring back order, and he's making progress.
• The short sentence shows how Scotland won't suffer for long. By defeating Macbeth, Scotland can be governed properly and flourish under divine authority.
• "I have no words; my voice is my sword". (act 5 Macduff).
