 Study Macbeth or William Shakespeare? Let's do some word-level analysis on the relationship between Macbeth and Banquo. In Act 1, scene 3, after they receive the witch's prophecy, Macbeth says your children shall be king, and the pronoun your shows his growing jealousy of Banquo. Yet Banquo responds with a declarative sentence, you shall be king, echoing Macbeth's words. However, we can see that he is not jealous at all of his friend. Macbeth's growing jealousy is shown even more when he asks the rhetorical question, do you not hope your children shall be kings? Yet Banquo remains loyal to his friend. He says the instruments of darkness tell us truths and win us with honest trifles, and the metaphor instruments of darkness show he does not trust the witches or the supernatural elements. The alliteration in Tell and Truths show Banquo does not trust the supernatural. He does not trust the intentions of the witches. He's simply saying that the witches will tell you a small truth so that they can win your trust, but once they win your trust, they will then betray you.
