Macbeth seeks out the witches again to learn more about his future. They give him three prophecies: 1) Beware Macduff; 2) None of woman born shall harm Macbeth; 3) Macbeth will not be defeated until Birnam Wood moves to Dunsinane. Macbeth feels reassured until he sees a vision of Banquo's descendants on the throne, which disturbs him. He curses the witches for misleading him with their predictions.
