Genesis 7:17-22

17For forty days the flood kept coming on the earth, and the waters rose and lifted the ark high above the earth. 18So the waters continued to surge and rise greatly on the earth, and the ark floated on the surface of the waters. 19Finally, the waters completely prevailed upon the earth, so that all the high mountains under all the heavens were covered.

20The waters rose and covered the mountaintops to a depth of fifteen cubits.1 21And every living thing that moved upon the earth perished—birds, livestock, animals, every creature that swarms upon the earth, and all mankind. 22Of all that was on dry land, everything that had the breath of life in its nostrils died.
