MACBETH

O, full of scorpions is my mind, dear wife!
Thou know'st that Banquo, and his Fleance, lives.

LADY MACBETH

But in them nature's copy's not eterne.

MACBETH

There's comfort yet; they are assailable;
Then be thou jocund: ere the bat hath flown
His cloister'd flight, ere to black Hecate's summons
The shard-borne beetle with his drowsy hums
Hath rung night's yawning peal, there shall be done
A deed of dreadful note.

LADY MACBETH

What's to be done?

MACBETH

Be innocent of the knowledge, dearest chuck,
Till thou applaud the deed. Come, seeling night,
Scarf up the tender eye of pitiful day;
And with thy bloody and invisible hand
Cancel and tear to pieces that great bond
Which keeps me pale! Light thickens; and the crow
Makes wing to the rooky wood:
Good things of day begin to droop and drowse;
While night's black agents to their preys do rouse.
Thou marvell'st at my words: but hold thee still;
Things bad begun make strong themselves by ill.
So, prithee, go with me.

Exeunt
