Shall come against him.

"Macbeth shall never vanquish'd be until Great Birnam Wood to high Dunsinane Hill shall come against him." Act 4, scene 1, line 91. Spoken by the third apparition, a supernatural figure conjured by the witches during Macbeth's second visit to them.
Meaning
- "Macbeth shall never vanquish'd be until Great Birnam Wood to high Dunsinane Hill shall come against him." - This prophecy tells Macbeth that he will not be defeated until Birnam Wood (a forest) moves to Dunsinane Hill (a castle sits on top of Dunsinane Hill in the play. Macbeth lives in this castle and it is where Macbeth kills King Duncan when he comes to stay).
- Macbeth interprets this literally, believing it's impossible for a forest to move, and therefore he thinks he's invincible. But, the prophecy is intentionally misleading. Later in the play, Malcolm's army cuts down branches from Birnam Wood and uses them as camouflage as they march to Dunsinane making it appear as though the forest is moving.
