Macbeth demands to know his fate and the witches provide him with the answer. The apparitions tell him to be wary, even though no one born from a woman would ever harm him
He is told too that he will never be defeated until Birnam Wood marches to fight him at Dunsinane Hill, which relieves him, as he finds such thing as impossible to happen
After that, he wants to know if Banquo´s kin will ever reign Scotland. He has a vision where Banquo and every Banquo´s descendants are sitting in thrones.
He can´t believe his eyes, he is frightened, but before he gets to ask for an explanation, the witches vanish as they dance.
Now Lennox enters and tells Macbeth that Macduff has fled to England
