FIRST WITCH: All hail, Macbeth! hail to thee, thane of Glamis!
SECOND WITCH: All hail, Macbeth, hail to thee, thane of Cawdor!
THIRD WITCH: All hail, Macbeth, thou shalt be king hereafter!
– William Shakespeare
Macbeth, Act 1, Scene 3. When Macbeth invites the Witches to speak, their words are prophetic and foreshadowing of things to come. They hail him as Thane of Cawdor, an example of dramatic irony since the audience already knows that but Macbeth does not. They also prophesy that he will be later become King of Scotland.
