Genesis 7:4

For yet seven days, and I will cause it to rain upon the earth forty days and forty nights; and every living substance that I have made will I destroy from off the face of the earth.

Notes:

“substance” here should be “thing”. God would cause a flood to kill every living “thing” from off the face of the earth. Just a side note: there are so many instances in the KJV bible of destroy that I can never be sure which were there originally and which weren’t.
