Genesis 7:10-12

10Now it came about after 1the seven days, that the waters of the flood 2came upon the earth. 11In the 3six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on that day all 4the fountains of the great deep burst open, and the 5floodgates of the sky were opened. 126The rain 7fell upon the earth for forty days and forty nights.
