Genesis 7:1, 4, 18-19

Then the LORD said to Noah, “I have seen that you are the best person among the people of this time, so you and your family can go into the boat.

Seven days from now I will send rain on the earth. It will rain forty days and forty nights, and I will wipe off from the earth every living thing that I have made.”

The water continued to rise, and the boat floated on it above the earth. The water rose so much that even the highest mountains under the sky were covered by it.
