Bring me no more reports; let them fly all:
Till Birnam wood remove to Dunsinane,
I cannot taint with fear. What's the boy Malcolm?
Was he not born of woman? The spirits that know
All mortal consequences have pronounced me thus:
'Fear not, Macbeth; no man that's born of woman
Shall e'er have power upon thee.' Then fly,
false thanes,
And mingle with the English epicures:
The mind I sway by and the heart I bear
Shall never sag with doubt nor shake with fear.
