'Flood' in the Bible

he is like a [far-sighted, practical, and sensible] man building a house, who dug deep and laid a foundation on the rock; and when a flood occurred, the torrent burst against that house and yet could not shake it, because it had been securely built and founded on the rock.

the people were eating, they were drinking, they were marrying, they were being given in marriage, [they were indifferent to God] until the day that Noah went into the ark, and the flood came and destroyed them all.
