Here is your answer.
Macbeth was a Scottish baron whose wife decided to kill him
after the predictions of witch that the Macbeth is going to become a king. Everyone
was in fear that who will be the next in the list of murders. Macbeth realizes that
the prediction is going to be true, so he committed murder to benefit the son
of Banquo. After this, the witch assured that none of woman born shall harm
Macbeth and also he will not become king. Further, Macduff and Malcolm march
towards the Macbeth and after the gathering in the Birnam Wood, there was an
order to cut down branches and use them to disguise the presence. However, the
prophecy that Birnam Wood will move against Dunsinane was the main concern.
