Genesis 7:1-4

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] Of every clean animal you shall take with you seven pair, the male and his female, and of animals that are not clean, two each the male and his female; [Lev 11:1-13] also of the birds of the air, seven pair, the male and the female, to keep the offspring alive on the surface of the earth. 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.”
