Glamis thou art, and Cawdor; and shalt be
What thou art promised.
– William Shakespeare
Macbeth, Act 1, Scene 5. Lady Macbeth is even more ambitious and resolved to succeed to the most powerful position in the land than her husband. She has just received a letter from Macbeth telling of the Witches’ prophecy. Her words from her soliloquy show that she is determined he will be king.
