Lady Macbeth

LADY MACBETH 
Out, damned spot! out, I say!--One: two: why, 
then, 'tis time to do't.--Hell is murky!--Fie, my 
lord, fie! a soldier, and afeard? What need we 
fear who knows it, when none can call our power to 
account?--Yet who would have thought the old man 
to have had so much blood in him. 

DOCTOR 
Do you mark that? 

LADY MACBETH 
The thane of Fife had a wife: where is she now?-- 
What, will these hands ne'er be clean?--No more o' 
that, my lord, no more o' that: you mar all with 
this starting.
