Yet know, my master, God omnipotent,
Is mustering in his clouds on our behalf
Armies of pestilence; and they shall strike
Your children yet unborn and unbegot,
That lift your vassal hands against my head
And threat the glory of my precious crown.
Tell Bolingbroke--for yond methinks he stands--
That every stride he makes upon my land
Is dangerous treason: he is come to open
The purple testament of bleeding war;
But ere the crown he looks for live in peace,
Ten thousand bloody crowns of mothers' sons
Shall ill become the flower of England's face,
Change the complexion of her maid-pale peace
To scarlet indignation and bedew
Her pastures' grass with faithful English blood.

-Richard III, act III, scene iii
