Here are where the 3 weird sisters show Macbeth the prophecy that he will be king, as they kept saying, "All hail, Macbeth! Hail to thee, Thane of Glamis!"
Act 3: Scene 4
Here, Macbeth is confused either to go through with it and kill Duncan, but he is worried where this path would take him. Lady Macbeth however, mocks him, saying he wouldnt be a man if he didnt go through with it.
Act 4: Scene 1
Here, he is going through and doing the prophecy that the three weird sisters told him. He is killing the King so that he may be Thane
Act 5: Scene 8
In this scene, Macbeth has already murdered his friend Banquo, and began to see his ghost sitting at the chair that Macbeth set up to make it seem like he didnt know Banquo was murdered. P.S, his wife had no idea of what Macbeth has done.
In this scene, the queen of witches (Hecate) asked the three weird sisters to give another prophecy to Macbeth that will ensure him safety. But he must kill Macduff for that safety.
Here in the final scene, Macduff avenges his wife and children by slaughtering Macbeth, and becoming the true king of the land!
