Whereby the world that then was, being overflowed with water, perished:
through which the world at that time was destroyed, being flooded with water.
and that by means of these the world that then existed was deluged with water and perished.
By these waters also the world of that time was deluged and destroyed.
by which the world that then existed perished, being flooded with water.
Then he used the water to destroy the ancient world with a mighty flood.
through which [waters] the then world, deluged with water, perished.
