And when the seas are kindled,
The oceans are set aflame
when the seas are set boiling
And when the cities are made to swell
And when/if the seas/oceans filled and over flowed
When the seas boil [due to the intense heat created by the explosion of sun]
And when the seas are set afire
And when the rivers are drained away
And when (all) oceans and rivers will be made to rise and swell
And when the rivers will be drained away
And when the seas shall become as blazing Fire or shall overflow
