Genesis 7:5-9

5And Noah did according to all that Jehovah had commanded him.

6And Noah was six hundred years old when the flood of waters was on the earth.

7And Noah went in, and his sons, and his wife, and his sons' wives with him, into the ark, because of the waters of the flood.

8Of clean beasts, and of beasts that are not clean, and of fowl, and of everything that creeps on the ground,

9there came two and two unto Noah into the ark, male and female, as 1God had commanded Noah.
