Genesis 7:1-4

1Then the Lord said to Noah, “Come into the ark, you and all your household, because I have seen that you are righteous before Me in this generation.

2You shall take with you seven each of every clean animal, a male and his female; two each of animals that are unclean, a male and his female;

3also seven each of birds of the air, male and female, to keep the species alive on the face of all the earth.

4For after seven more days I will cause it to rain on the earth forty days and forty nights, and I will destroy from the face of the earth all living things that I have made.”
