It's actually and simply the AvB version of the traditional hymn "Jerusalem" - great version though by Armin...
The music was written by Sir Hubert Parry in 1916, and the words in the original version is taken from a poem by William Blake ca. 1804.
It was also popularized when it was featured in the Vangelis OST "Chariots Of Fire" in 1981.
The original lyrics i.e. poem by William Blake is as follows:
"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."
