Blood and Sleep

Sleep: 

``Then live, Macduff. What need I fear of thee?

But yet I’ll make assurance double sure,

And take a bond of fate. Thou shalt not live,

That I may tell pale-hearted fear it lies,

And sleep in spite of thunder.`` (4.1 85)

He doesn`t need to kill Macduff. He has no reason to fear him, and he will make sure of that, he will even guarantee his own fate by killing him. if he does that, he can conquer his fear and sleep easily tonight.

 

Blood:

     ``Bleed, bleed, poor country!

Great tyranny, lay thou thy basis sure,

For goodness dare not check thee. Wear thou thy wrongs;

The title is affeered.—Fare thee well, lord.

I would not be the villain that thou think’st

For the whole space that’s in the tyrant’s grasp,

And the rich East to boot.``

Bleed, bleed, poor country! He is saying to go ahead and build himself up because people are afraid to stand up to him. His title is safe so he should enjoy everything he has.
