Genesis 7:11-24

In the six hundredth year of Noah’s life, on the seventeenth day of the second month, on that same day all the fountains of the great deep [subterranean waters] burst open, and the windows and floodgates of the heavens were opened. It rained on the earth for forty days and forty nights. On the very same day Noah and Shem and Ham and Japheth, the sons of Noah, and Noah’s wife and the three wives of his sons with them, entered the ark, they and every animal according to its kind, all the livestock according to their kinds, every moving thing that crawls on the earth according to its kind, and every bird according to its kind, every winged thing of every sort. So they went into the ark with Noah, two by two of all living beings in which there was the breath and spirit of life. Those which entered, male and female of all flesh (creatures), entered as God had commanded Noah; and the LORD closed the door behind him. The 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. The waters became mighty and increased greatly on the earth, and the ark floated on the surface of the waters. The 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. [In fact] the waters became fifteen cubits higher [than the highest ground], and the mountains were covered. All 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. Everything on the dry land, all in whose nostrils was the breath and spirit of life, died. God destroyed (blotted out, wiped away) every living thing that was on the surface of the earth; man and animals and the crawling things and the birds of the heavens were destroyed from the land. Only Noah and those who were with him in the ark remained alive. [Matt 24:37-44] The waters covered [all of] the earth for a hundred and fifty days (five months).
