Genesis 7:10

8Clean animals, unclean animals, birds, and everything that creeps on the ground

9went by pairs to Noah into the ship, male and female, as God commanded Noah.

10After the seven days, the floodwaters came on the earth.

11In 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 sky’s windows opened.

12It rained on the earth forty days and forty nights.
