Genesis 7:1-5

When everything was ready, the LORD said to Noah, “Go into the boat with all your family, for among all the people of the earth, I can see that you alone are righteous. Take with you seven pairs—male and female—of each animal I have approved for eating and for sacrifice, and take one pair of each of the others. Also take seven pairs of every kind of bird. There must be a male and a female in each pair to ensure that all life will survive on the earth after the flood. Seven days from now I will make the rains pour down on the earth. And it will rain for forty days and forty nights, until I have wiped from the earth all the living things I have created.” So Noah did everything as the LORD commanded him.
