TSK · Genesis 7:8

Of every living thing of all flesh, you shall bring two of every sort into the ship, to keep them alive with you. They shall be male and female.

You shall take seven pairs of every clean animal with you, the male and his female. Of the animals that are not clean, take two, the male and his female.

in which were all kinds of four-footed animals of the earth, wild animals, reptiles, and birds of the sky.
