Genesis 7:1, 4, 18-19

Then the LORD said to Noah, “Come into the ark, you with all your household, for you [alone] I have seen as righteous (doing what is right) before Me in this generation. [Ps 27:5; 33:18, 19; 2 Pet 2:9]

For in seven days I am going to cause it to rain on the earth for forty days and forty nights; and I will destroy (blot out, wipe away) every living thing that I have made from the surface of the earth.”

The waters became mighty and increased greatly on the earth, and the ark floated on the surface of the waters. The waters prevailed so greatly and were so mighty and overwhelming on the earth, so that all the high mountains everywhere under the heavens were covered.
