TSK · Genesis 7:8

And of every living thing of all flesh, two of every sort shalt thou bring into the ark, to keep them alive with thee; they shall be male and female.

Of every clean beast thou shalt take to thee seven and seven, the male and his female; and of the beasts that are not clean two, the male and his female:

wherein were all manner of fourfooted beasts and creeping things of the earth and birds of the heaven.
