Genesis 7:4, 12, 17
For seven days from now I will send rain on the earth for forty days and forty nights, and I will wipe from the face of the earth every living thing I have made.” / And the rain fell upon the earth for forty days and forty nights. / For forty days the flood kept coming on the earth, and the waters rose and lifted the ark high above the earth.
