“And after seven days the waters of the flood came on the earth. In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst forth and the windows of the heavens were opened. The rain fell upon the earth forty days and forty nights. On the very same day Noah and his sons, Shem and Ham and Japheth, and Noah’s wife and the three wives of his sons with them entered the ark, they and every animal of every kind, and all the domestic animals of every kind, and every creeping thing that creeps on the earth, and every bird of every kind, every bird, every winged creature. They went into the ark with Noah, two and two of all flesh in which there was the breath of life. And those that entered, male and female of all flesh, went in as God had commanded him. And Yahweh shut him in.”
On the 17th day of the second month the mythic flood began as the fountains burst with rain for forty days and nights. This was a crowded ship even though there is no indication of any children of the three sons. The heavens opened with rain.
“The flood continued forty days on the earth. The waters increased, and bore up the ark, and it rose high above the earth. The waters swelled and increased greatly on the earth. The ark floated on the face of the waters. The waters swelled so mightily upon the earth that all the high mountains under the whole heaven were covered. The waters swelled above the mountains, covering them fifteen cubits deep. And all flesh died that moved on the earth, birds, domestic animals, wild animals, all swarming creatures that swarm on the earth, and all human beings. Everything on dry land in whose nostrils was the breath of life died. He blotted out every living thing that was on the face of the ground, human beings and animals and creeping things and birds of the air. They were blotted out from the earth. Only Noah was left, and those that were with him in the ark. And the waters swelled on the earth for one hundred and fifty days.”
God destroyed all these humans and all breathing animals because they were evil, something that becomes a metaphor of things to come. During the forty days, the ark floated over the mountains. Everything not in the ark died. Only those on the ark with Noah were saved. The waters continued to swell for 150 days, after the 40 day deluge.
