In Act Two, Scene One of William Shakespeare's play "Macbeth," the titular character offers Lord Banquo, a fellow general for King Duncan, an unspecified reward in exchange for allegiance to Macbeth's plots. This is essentially a bribe, as Macbeth desires Banquo's support for the purpose of becoming king.
Although Banquo is not explicitly aware of the witches' prophecy that Macbeth will be king, he responds to Macbeth's offer with uneasiness. He senses that Macbeth has some ulterior motive in mind and is concerned that supporting Macbeth may lead to dishonorable actions. In his line, he subtly suggests as such to Macbeth, who is nearly insulted by the remark. This scene represents a break between the two characters; Macbeth grows to distrust Banquo and has him murdered.
