In 'Macbeth,' prior to the war, Macbeth is given prophecies which he considers make him pretty much invincible. However, the prophecies have hidden meaning. For example, he is told that he will have trouble only if Birnam Woods come to him. Macbeth feels its impossible for the woods to come after him. However, the oncoming soldiers take branches from the wood to use as camouflage. He is also told that no man born of woman can kill him. Again, he thinks all men are born of women, so he's invincible. However, right before Macduff cuts off Macbeth's head, he tells him he was basically ripped from his mother's body by Caesarian section.
