Enter Malcolm and Donalbain.

DONALBAIN.
What is amiss?

MACBETH.
You are, and do not know’t:
The spring, the head, the fountain of your blood
Is stopp’d; the very source of it is stopp’d.

MACDUFF.
Your royal father’s murder’d.

MALCOLM.
O, by whom?

LENNOX.
Those of his chamber, as it seem’d, had done’t:
Their hands and faces were all badg’d with blood;
So were their daggers, which, unwip’d, we found
Upon their pillows. They star’d, and were distracted;
No man’s life was to be trusted with them.

MACBETH.
O, yet I do repent me of my fury,
That I did kill them.

MACDUFF.
Wherefore did you so?

MACBETH.
Who can be wise, amaz’d, temperate, and furious,
Loyal and neutral, in a moment? No man:
Th’ expedition of my violent love
Outrun the pauser, reason. Here lay Duncan,
His silver skin lac’d with his golden blood;
And his gash’d stabs look’d like a breach in nature
For ruin’s wasteful entrance: there, the murderers,
Steep’d in the colours of their trade, their daggers
Unmannerly breech’d with gore. Who could refrain,
That had a heart to love, and in that heart
Courage to make’s love known?

LADY MACBETH.
Help me hence, ho!
