Genesis 7:15

It rained on the earth forty days and forty nights.

In the same day Noah, and Shem, Ham, and Japheth—the sons of Noah—and Noah’s wife and the three wives of his sons with them, entered into the ship—

they, and every animal after its kind, all the livestock after their kind, every creeping thing that creeps on the earth after its kind, and every bird after its kind, every bird of every sort.

Those who went in, went in male and female of all flesh, as God commanded him; then the LORD shut him in.

The flood was forty days on the earth. The waters increased, and lifted up the ship, and it was lifted up above the earth.

The waters rose, and increased greatly on the earth; and the ship floated on the surface of the waters.
