Genesis 7:1-5
"Then 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.'"
"'You 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.'"
"'Also seven each of birds of the air, male and female, to keep the species alive on the face of all the earth.'"
"'For 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.'"
"And Noah did according to all that the Lord commanded him."
