Genesis 7:17-23

17For forty days the flood kept coming on the earth, and as the waters increased they lifted the ark high above the earth. 18The waters rose and increased greatly on the earth, and the ark floated on the surface of the water. 19They rose greatly on the earth, and all the high mountains under the entire heavens were covered. 20The waters rose and covered the mountains to a depth of more than fifteen cubits. That is, about 23 feet or about 6.8 meters Or rose more than fifteen cubits, and the mountains were covered 21Every living thing that moved on land perished—birds, livestock, wild animals, all the creatures that swarm over the earth, and all mankind. 22Everything on dry land that had the breath of life in its nostrils died.

23Every living thing on the face of the earth was wiped out; people and animals and the creatures that move along the ground and the birds were wiped from the earth. Only Noah was left, and those with him in the ark.
