And when the mountains are blown away as dust.
The mountains are blown up
and the mountains scattered
And when the mountains are carried away as dust
And when/if the mountains were uprooted and dispersed/exploded
When the mountains are reduced to dust
And when the mountains are made into dust and blown away
And when the mountains are blown away like dust
And when the mountains will be (broken down to dust) and blown off
And when the mountains shall be blown down to pieces
And when the mountains are blown away
