I drink to the general joy o’ th’ whole table, / And to our dear friend Banquo, whom we miss: / Would he were here.
Act III, Scene 4 · Macbeth
Context
Macbeth, trying to appear normal to his guests, proposes a toast to the absent Banquo, expressing a wish that he were present.
Analysis
Macbeth's toast is thick with situational irony—he toasts the man he has just had murdered and says 'Would he were here' at the exact moment Banquo's ghost is sitting at the table. The phrase 'whom we miss' is unintentionally true: Macbeth does 'miss' Banquo, in the sense that Fleance escaped. Shakespeare layers meanings so that Macbeth's performance of innocence becomes an accidental confession.
Essay Tip
Support a thesis that Macbeth's public language constantly betrays him—his attempt to sound innocent backfires because the words he chooses carry unintended meanings that expose his guilt.
