What happens

Macbeth visits the witches in their cave, where they conjure three apparitions to answer his questions. The first warns him to beware Macduff; the second assures him that no man born of woman can harm him; the third promises he'll be safe until Birnam Wood moves to Dunsinane. A vision of eight kings follows, suggesting Banquo's line will rule. Macbeth leaves emboldened, then learns Macduff has fled to England and decides to slaughter Macduff's entire family.

Why it matters

The witches' apparitions appear to give Macbeth exactly what he wants to hear—safety and invulnerability. But they are carefully worded equivocations designed to trap him. The second apparition's promise that 'none of woman born / Shall harm Macbeth' sounds absolute, yet it hinges on an impossible condition that will prove untrue. The third apparition's prophecy that he's safe 'till Birnam wood to high Dunsinane hill / Shall come' seems to guarantee his reign forever, since forests cannot move. Yet both conditions will be fulfilled in ways Macbeth cannot foresee. The witches speak truth that serves as a disguise for falsehood—a central mechanism of the play's exploration of how language can deceive.

Macbeth's response to the apparitions reveals his moral descent. Rather than treating the warnings with caution, he uses them to justify further murder. Learning that Macduff has fled to England, he immediately resolves to 'seize upon Fife' and 'give to the edge o' the sword / His wife, his babes, and all unfortunate souls.' The murder of innocents—children and women—marks a new depth of cruelty. Where earlier murders had pretexts of political necessity, this one is pure vengeance against an imagined threat. The apparitions haven't made Macbeth safer; they've made him more desperate and murderous, driving events toward the very prophecy he seeks to prevent.

Key quotes from this scene

Be bloody, bold, and resolute; laugh to scorn The power of man, for none of woman born Shall harm Macbeth.

Be violent, brave, and determined; laugh at the power of men, because no one born of a woman will ever harm Macbeth.

Second Apparition · Act 4, Scene 1

The witches' second apparition gives Macbeth what seems like certain protection. Macbeth believes himself invulnerable and relaxes his guard, ordering the murder of Macduff's family. The irony—that Macduff was untimely ripped from his mother's womb—is the engine of the play's final tragedy, showing how our attempt to escape fate binds us to it.

Double, double toil and trouble; Fire burn, and cauldron bubble.

Double, double, trouble and work; Fire burn, and cauldron bubble.

All (Chorus) · Act 4, Scene 1

The witches chant over their boiling cauldron as they prepare the magical brews that will summon the apparitions Macbeth demands. The line has become the signature incantation of witchcraft itself, repeated and parodied for four centuries. It captures the play's central engine: supernatural forces that speak in riddles and seem to grant wishes while actually leading their believers toward ruin.
