I'll go no more: | am afraid to think what I have done; Look on't again I dare not.
Infirm of purpose!Give me the daggers: the sleeping and the dead are but as pictures: 'tis the eye of childhood that fears a painted devil.If he do bleed, I'll gild the faces of the grooms withal; For it must seem their guilt.
Whence is that knocking? How is't with me, when every noise appals me? What hands are here? Ha! they pluck out mine eyes. Will all great Neptune's oceans wash this blood clean from my hands? No, this my hand with rather the multitudinous seas in incarnadine, Making the green one red.
My hands are of your colour; but I shame to wear a heart so white.
Macbeth admits to being afraid of going back to where he committed the murder.Lady Macbeth insults Macbeths by calling him a coward, and takes the daggers, claiming that it was essential to use the blood on the daggers to paint the servants' face with it in order to make them seem guilty. She mocks Macbeth by telling him that the dead can't cause hurt and only children are afraid of such things.
I hear a knocking at the south entry: retire we to our chamber; A little water clears us of our deed: How easy is it, then! Your constancy hath left you unattended.
Macbeth continues to be frightened of every noise he hears and wonders if even the water of all the seas would ever be able to cleanse his bloodied hands.
Hark! more knocking. Get on your nightgown lest occasion call us, And show us to be watchers. Be not lost so poorly in your thoughts.
Lady Macbeth scornfully tells Macbeth that she isn't even close to being as afraid as he seems.
To know my deed, 'twere best not know myself.Wake Duncan with thy knocking! I would thou could'st
Lady Macbeth hears someone knocking at the south entry and asks Macbeth to accompany her back to their bedroom. She tells him that water would wash away the evidence of their guilt.
She advises him to change into his bed-clothes and regain his senses.
Macbeth, however, wishes that he were unconscious so that he wouldn't have to think about the horrific deed.
