LADY MACBETH.
We fail!
But screw your courage to the sticking-place,
And we'll not fail. When Duncan is asleep,--
Whereto the rather shall his day's hard journey
Soundly invite him, his two chamberlains
Will I with wine and wassail so convince
That memory, the warder of the brain,
Shall be a fume, and the receipt of reason
A limbec only: when in swinish sleep
Their drenched natures lie as in a death,
What cannot you and I perform upon
The unguarded Duncan? what not put upon
His spongy officers; who shall bear the guilt
Of our great quell?

MACBETH.
Bring forth men-children only;
For thy undaunted mettle should compose
Nothing but males. Will it not be receiv'd,
When we have mark'd with blood those sleepy two
Of his own chamber, and us'd their very daggers,
That they have don't?

LADY MACBETH.
Who dares receive it other,
As we shall make our griefs and clamor roar
Upon his death?

MACBETH.
