Witches Idiom

Deeply Hidden in the mire,
We three witches do conspire.
With our black cauldron bring,
The thick black water from the devils spring.
With eagle eye and tongue from cat,
We mix these ingredients with the hair of a gnat.
As our mixture comes to boil,
Simply add in corpses soil.
Blood of newborn tail of deer,
For this potion takes away fear.
Macduff fear not Macbeth and his deeds,
For you were not born of woman but of mans seed.
Mix it good stir it well,
For this spell comes straight from hell.
Now let us rest our deed is done,
There will be a new king before the rising sun.
