[Thunder and lightning; three witches enter.]
When shall we three meet again —
In thunder, lightning, or in rain?
When the hurlyburly's done,
When the battle's lost, and won.
That will be ere the set of sun.
Where the place?
Upon the heath.
There to meet with Macbeth.
I come, Graymalkin.
Fair is foul, and foul is fair.
Hover through the fog and filthy air.
