The Witches meet on the dark and lonely heath to await Macbeth. Macbeth and Banquo come across the Weird Sisters and we see immediately that Macbeth has a strange connection to the Witches, mimicking their famous words spoken earlier in the drama: "So foul and fair a day I have not seen"(1.3.38) . The Witches address Macbeth as Glamis, Cawdor, and King of the Scots. Macbeth is startled by what he sees clearly as a prophecy that he will be Scotland's next ruler. He is too stunned to speak and thus Banquo asks the Witches if there is any more to their premonition. They do have something to add, not about Macbeth, but about Banquo .
the Witches promise Macbeth that his descendants will be future kings of Scotland. the second witch great Macbeth saying "all hail, Macbeth hail to thee, thane of Cawdor " when the witches start to prophesies Macbeth future, Macbeth is already thane of Glamis, and the witches telling him his going to be thane of Cawdor plants the idea in his mind, which will lead him to become the than of Cawdor.Also, They promised Banque that he'd be less powerful than Macbeth, but a better person; not as happy with his job but happier overall; and that his sons would be kings.Macbeth reaction toward the three witches prophecy .After the witches make their predictions to Macbeth is Banquo who asks, essentially, "What about me?!" They gave his friend such great news, he doesn't want to miss out on any good news for himself. After the witches give Banquo his predictions, Macbeth tries to ask them to explain how what they said can be true? But, the witches disappear, leaving a bemused (puzzled) pair to wonder aloud if they had just been seeing things, or if they really had been visited by something supernatural. Then come these two lines: MACBETH: Your children shall be kings. BANQUO: You shall be king.
Macbeth, amazed that the witches’ prophecy has come true, asks Banquo if he hopes his children will be kings. Banquo replies that devils often tell half-truths in order to “win us to our harm” (1.3.121). Macbeth ignores his companions and speaks to himself, ruminating upon the possibility that he might one day be king. He wonders whether the reign will simply fall to him or whether he will have to perform a dark deed in to gain the crown. At last he shakes himself from his reverie and the group departs for Forres. As they leave, Macbeth whispers to Banquo that, at a later time, he would like to speak to him privately about what has transpired.
I can just see them kind of elbowing one another and grinning at the prospects ahead of them. It's one of the last times things will ever be so carefree and friendly between them.
