Quotations

"Glamis thou art, and Cawdor, and shalt be What thou art promised" (31). This is a quote from the scene in which Lady MacBeth begins her scheming. This was right after she read the letter from MacBeth informing her about his meeting the witches. This is when Lady MacBeth starts to fear that her husband will be too innocent to murder King Duncan, which he will have to do in order to become King of Scotland.

"Thou mayst revenge--O slave!" (97). These are Banquo's dying words, he says them to his son just after he is murdered by the murderers hired by MacBeth. This is why Fleance was unable to defend himself against the allegations that he killed his father. This is also how the witches prophecy will come to be because Banquo still has living descendants. I believe that because we already know that MacDuff will kill MacBeth and become a king with no heirs, that he will name Fleance his heir to the throne, bringing the prophecy full circle.
