Macbeth: Extracted from Act II, Scene i

MACBETH.
I heard a voice cry, “Sleep no more!
Macbeth does murder sleep,”--the innocent sleep;
Sleep that knits up the ravell’d sleave of care,
The death of each day’s life, sore labour’s bath,
Balm of hurt minds, great nature’s second course,
Chief nourisher in life's feast.


LADY MACBETH.
What do you mean?

MACBETH.Still it cried, “Sleep no more!” to all the house:
“Glamis hath murder'd sleep, and therefore Cawdor
Shall sleep no more,--Macbeth shall sleep no more!”

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?
