Genesis 7:1-5

Then the LORD said to Noah, “Enter the ark, you and all your household, for I have seen that you alone are righteous before Me in this generation. You are to take with you seven pairs, a male and its female, of all the clean animals, and two of the animals that are not clean, a male and its female, and seven pairs, male and female, of the birds of the sky — in order to keep offspring alive on the face of the whole earth. Seven days from now I will make it rain on the earth 40 days and 40 nights, and I will wipe off from the face of the earth every living thing I have made.” And Noah did everything that the LORD commanded him.
