This disease is beyond my practice

Doctor
This disease is beyond my practice. Yet I have
known those which have walked in their sleep,
who have died holily in their beds.
Lady Macbeth
Wash your hands. Put on your nightgown.
Look not so pale. I tell you yet again, Banquo’s
buried; he cannot come out on ’s grave.
Doctor
Even so?

Foul whisp’rings are abroad. Unnatural deeds
Do breed unnatural troubles.

Lady Macbeth
To bed, to bed. There’s knocking at the
gate. Come, come, come, come. Give me your
hand. What’s done cannot be undone. To bed, to
bed, to bed.
 Lady Macbeth exits.
Doctor
Will she go now to bed?
Gentlewoman
Directly.
Doctor
Foul whisp’rings are abroad. Unnatural deeds
Do breed unnatural troubles. Infected minds
To their deaf pillows will discharge their secrets.
More needs she the divine than the physician.
God, God forgive us all. Look after her.
Remove from her the means of all annoyance
And still keep eyes upon her. So, good night.
My mind she has mated, and amazed my sight.
I think but dare not speak.
Gentlewoman
Good night, good doctor.
 They exit.
