'Flash' in the Bible

For the stars of heaven and their constellationsWill not flash forth their light;The sun will be dark when it risesAnd the moon will not shed its light.

But the horde of invaders will be like fine dust, the horde of tyrants like chaff that is blown away. It will happen suddenly, in a flash.

So this sin will become your downfall. You will be like a high wall that bulges and cracks and is ready to collapse; it crumbles suddenly, in a flash.
