Genesis 7:1-3

Then the LORD said to Noah, “I have seen that you are the best person among the people of this time, so you and your family can go into the boat. Take with you seven pairs, each male with its female, of every kind of clean animal, and take one pair, each male with its female, of every kind of unclean animal. Take seven pairs of all the birds of the sky, each male with its female. This will allow all these animals to continue living on the earth after the flood.
