Genesis 7:17-22

17The flood [the great downpour of rain] was forty days and nights on the earth; and the waters increased and lifted up the ark, and it floated [high] above the land.

18The waters became mighty and increased greatly on the earth, and the ark floated on the surface of the waters.

19The waters prevailed so greatly and were so mighty and overwhelming on the earth, so that all the high mountains everywhere under the heavens were covered.

20[In fact] the waters became fifteen cubits higher [than the highest ground], and the mountains were covered.

21All living beings that moved on the earth perished—birds and cattle (domestic animals), [wild] animals, all things that swarm and crawl on the earth, and all mankind.

22Everything on the dry land, all in whose nostrils was the breath and spirit of life, died.
