That which hath made them drunk hath made me bold. What hath quenched them hath qiven me fire.
Why did you bring these daggers from the place?They must lie there. Go carry them and smear the sleepy grooms with blood.
I have done the deed. Didst thou not hear a noise?
I’ll go no more:I am afraid to think what I have done;Look on ’t again I dare not.
Infirm of purpose! Give me the daggers. If he do bleed,I’ll gild the faces of the grooms withal,For it must seem their guilt.
Lady Macbeth is explaining how bold she is feeling as she follows through with her part of the plan to kill King Dunccan, by poisoning the sleeping chamberlains
How is ’t with me when every noise appalls me?
Macbeth confirms with Lady Macbeth that he has killed the King and that he has been hearing strange noises ever since. Lady Macbeth brushes his worries aside and asks for him to plant the dagger used to kill the King with the guards.
My hands are of your color, but I shame.To wear a heart so white.
As Macbeth expresses that he cannot place the daggers back in the room where the chamberlains are since he cannot face his actions, Lady Macbeth does it and shames his conscious.
To know my deed, ’twere best not know myself.
Macbeth questions his mentality since he jumps to strange conclusions at every sound he hears.
Lady Macbeth retorts that even though they both committed the same crime, her conscious is not letting her feel guilt.
Macbeth exclaims that it is better for him to be unconscious or dead since he cannot bear to think of his actions.
