Genesis 7:17-22

Water flooded the earth for forty days, and as it rose it lifted the boat off the ground. The water continued to rise, and the boat floated on it above the earth. The water rose so much that even the highest mountains under the sky were covered by it. It continued to rise until it was more than twenty feet above the mountains. All living things that moved on the earth died. This included all the birds, tame animals, wild animals, and creatures that swarm on the earth, as well as all human beings. So everything on dry land that had the breath of life in it died.
