Genesis 7:6-12

6Now Noah was 600 years old when the floodwaters came upon the earth. 7And Noah and his wife, with his sons and their wives, entered the ark to escape the waters of the flood. 8The clean and unclean animals, the birds, and everything that crawls along the ground 9came to Noah to enter the ark, two by two, male and female, as God had commanded Noah.

10And after seven days the floodwaters came upon the earth. 11In the six hundredth year of Noah’s life, on the seventeenth day of the second month, all the fountains of the great deep burst forth, and the floodgates of the heavens were opened. 12And the rain fell upon the earth for forty days and forty nights.
