Banquo, would you and Fleance come back to Candor for a feast tonight?
"Thou hast it now—king, Cawdor, Glamis, allAs the Weïrd Women promised, and I fearThou played’st most foully for ’t."
Yes, I will be there, my lord.
Bring the two men waiting for me before us, please.
Yes, my lord.
Banquo sees that the witches' prophecy has come true, and is suspicious of Macbeth, but he remembers that the witches also predicted that his own children would be heirs to the throne.
"There is none but [Banquo]Whose being I do fear; and under himMy genius is rebuked, as it is said Mark Antony’s was by Caesar. He chid the sistersWhen first they put the name of king upon meAnd bade them speak to him. Then, prophet-like,They hailed him father to a line of kings."
Macbeth and his wife, now the king and queen, ask Banquo to a feast at the castle later that night. Macbeth mentions that the sons of the late King Duncan have fled and not confessed "their sins."
Have you thought about what I told you? Has it not been Banquo who wronged you so many times?
Yes. We will carry through with your plans, my lord.
As lady and Macbeth, Lennox, Ross, the lords, the attendants, and Banquo exit, Macbeth asks his servant to bring in the two men waiting for him.
You are to wait in the castle until you receive an order from me.
Macbeth fears Banquo is suspicious of him, and he fears that the witches' prophecy is true, meaning his own sons will never be heir to the throne.
Macbeth talks to the two men the servant brought in to him, and he reminds them of the conversation they had the day before. Macbeth reminded them of all the times Banquo had wronged them in their past, and asked the two men to murder Banquo and his son.
Macbeth tells the two murderers to wait inside the castle for his next order, when he will direct them to kill Banquo.
