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 those 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 & pleasant Land
William Blake

Beneath this poem Blake inscribed “Would to God that all the Lord’s people were Prophets” (Numbers 11:29)

Prophecy for Blake was not a prediction of the end of the world, but telling the truth as best a person can about what he or she sees, fortified by insight and an “honest persuasion” that with personal struggle, things could be improved. A human being observes, is indignant and speaks out: it’s a basic political maxim which is necessary for any age. Blake wanted to stir people from their intellectual slumbers, and the daily grind of their toil, to see that they were captivated in the grip of a culture which kept them thinking in ways which served the interests of the powerful.
