Lady Macbeth
Who was it that thus cried? Why, worthy thane,
You do unbend your noble strength, to think
So brainsickly of things. Go get some water,
And wash this filthy witness from your hand.
Why did you bring these daggers from the place?
They must lie there: go carry them; and smear
The sleepy grooms with blood.
Macbeth
I’ll go no more:
I am afraid to think what I have done;
Look on’t again I dare not.
Lady Macbeth
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;
