From ‘Milton’

AND did those feet in ancient time 
  Walk upon England’s mountains green? 
And was the holy Lamb of God 
  On England’s pleasant pastures seen? 
 
And did the Countenance Divine 
  Shine forth upon our clouded hills? 
And was Jerusalem builded here 
  Among these dark Satanic Mills? 
 
Bring me my bow of burning gold! 
  Bring me my arrows of desire! 
Bring me my spear! O clouds, unfold! 
  Bring me my chariot of fire! 
 
I will not cease from mental fight, 
  Nor shall my sword sleep in my hand, 
Till we have built Jerusalem 
  In England’s green and pleasant land.
