Genesis 7:9-12

9male and female, came to Noah and entered the ark, as God had commanded Noah.

10And after the seven days the floodwaters came on the earth. 11In the six hundredth year of Noah’s life, on the seventeenth day of the second month—on that day all the springs of the great deep burst forth, and the floodgates of the heavens were opened.

12And rain fell on the earth forty days and forty nights.
