The love-diffusing [Lord] will separate us.
The land of worldly weather,
A wind will melt the trees:
There will pass away every tranquillity
When the mountains are burnt.
There will be again inhabitants
With horns before kings;
The mighty One will send them,
Sea, and land, and lake.
There will be again a trembling terror,
And a moving of the earth,
And above every field,
And ashes the rocks will be;
With violent exertion, concealment,
And burning of lake.
