Macbeth Quote Analysis

Malcolm is testing Macduff's loyalty by questioning why he left Scotland. Here Malcolm refers to Macbeth, reminding Macduff that even the tyrant was once trusted.

The violent metaphor 'blisters our tongues' makes speech itself painful—simply naming Macbeth becomes a physical injury. This isn't just hyperbole; it registers how tyranny contaminates language, making even the act of reference feel like complicity. The juxtaposition with 'once thought honest' reminds us that reputations can rot completely, priming Malcolm's later test of whether Macduff might similarly be deceiving him.

Support a thesis that Shakespeare uses physical disgust (blistering) to show how evil rulers don't just harm people—they poison the very medium (language) through which communities hold leaders accountable.
