Genesis 7:8-12

Of clean animals and animals that are not clean and birds and everything that crawls on the ground,

they all went into the ark to Noah by twos, male and female, as God had commanded Noah.

Now it came about after the seven days, that the waters of the flood came upon 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 open, and the floodgates of the sky were opened.

The rain fell upon the earth for forty days and forty nights.
