7:4 For in seven days ¹  I will cause it to rain ²  on the earth for forty days and forty nights, and I will wipe from the face of the ground every living thing that I have made.”

Genesis 7:17

7:17 The flood engulfed the earth for forty days. As the waters increased, they lifted the ark and raised it above the earth.
