"That which hath made them drunk hath made me bold."
"And ;tis not done. Th' attempt and not the deed"
"Alack, I am afraid they have awaked"
"I have done the deed."
"This is a sorry sight"
"Why did you bring these daggers from the place?They must lie there: go carry them; and smear The sleepy grooms with blood."
"A foolish thought, to say a sorry sight.
Lady Macbeth has just drugged king Duncans servants. While she is talking about what she has done, she hears a voice from out side and fears she has been caught.
"I'll go no more:I am afraid to think what I have done; Look on't again I dare not.
Give me the daggers: the sleeping and the deadAre but as pictures: 'tis the eye of childhoodThat fears a painted devil. If he do bleed,I'll gild the faces of the grooms withal; For it must seem their guilt.
Lady Macbeth fears that Macbeth has failed his deed and that their plan has been discovered.
"Will all great Neptune's ocean wash this bloodClean from my hand? No, this my hand will ratherThe multitudinous seas in incarnadine,Making the green one red."
(Enter Macbeth, with bloody daggers) Lady Macbeth is angry because Macbeth didn't leave the dagger with the servants.
"I hear a knockingAt the south entry: retire we to our chamber;A little water clears us of this deed:How easy is it, then! Your constancy Hath left you unattended.
Macbeth isn't able to continue with the plan and face what he has done. Lady Macbeth gets angry and decides to go plant the dagger by herself.
Lady Macbeth leaves to go plant the dagger, while Macbeth struggles to come to terms with what he has done and is full of guilt and fear.
Lady Macbeth returns as there is a knocking on the door. She orders Macbeth to go get dressed quickly so they can pretend they have been sleeping. (End of scene 2)
