1. "All hail, Macbeth, that shalt be king hereafter!" This is the most important message, predicting that Macbeth will become King of Scotland.
2. "All hail, Macbeth, thou shalt be king hereafter!" This is a repetition of the first message, emphasizing the certainty of the prophecy.
3. "All hail, Macbeth, that shalt be king hereafter! / Thou shalt get kings, though thou be none: / So all hail, Macbeth and Banquo!" This message prophesies that Macbeth's descendants will become kings, even though he himself will not be a true king. It also acknowledges Banquo, who will have a significant role in the future.
These messages are the catalyst for Macbeth's ambition and his tragic downfall.
