Genesis 7:13-16

That very day Noah had gone into the boat with his wife and his sons—Shem, Ham, and Japheth—and their wives. With them in the boat were pairs of every kind of animal—domestic and wild, large and small—along with birds of every kind. Two by two they came into the boat, representing every living thing that breathes. A male and female of each kind entered, just as God had commanded Noah. Then the LORD closed the door behind them.
