Deception in Macbeth

Left alone, Macbeth summons the two murderers he has hired. While he waits for them, he voices his greatest worry of the moment—that the witches' prophecy will also come true for Banquo, making his children kings. He will put an end to such worries by hiring two men to kill Banquo and Fleance. Macbeth will act like he honors Banquo while plotting to kill him.
