- The witches' prophesy that Macbeth will be king, which alludes to James's claim to the English throne after the death of Queen Elizabeth I.
- Macbeth's description of the witches as "weird sisters," which echoes the belief that James had the power to control witches and spirits.
- The portrayal of Banquo as a noble and virtuous character, which was likely meant to please James, who was a direct descendant of Banquo.
These additions were likely meant to curry favor with James and ensure that the play would be well-received by the court.
