Genesis

And they went in unto Noah into the ark, two and two of all flesh, wherein is the breath of life.

And they that went in, went in male and female of all flesh, as God had commanded him: and the Lord shut him in.

Of clean beasts, and of beasts that are not clean, and of fowls, and of every thing that creepeth upon the earth,

There went in two and two unto Noah into the ark, the male and the female, as God had commanded Noah.

Bring forth with thee every living thing that is with thee, of all flesh, both of fowl, and of cattle, and of every creeping thing that creepeth upon the earth; that they may breed abundantly in the earth, and be fruitful, and multiply upon the earth.
