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.
