Leviticus 11:5

“You shall take with you of every clean animal by sevens, a male and his female; and of the animals that are not clean, two, a male and his female;

Then Noah built an altar to Yahweh and took of every clean animal and of every clean bird and offered burnt offerings on the altar.

‘You are therefore to separate between the clean animal and the unclean, and between the unclean bird and the clean; and you shall not make yourselves detestable by animal or by bird or by anything that creeps on the ground, which I have separated for you as unclean.

“These are the animals which you may eat: the ox, the sheep, the goat,

The high mountains are for the wild goats; The cliffs are a refuge for the shephanim.

The shephanim are not a mighty people, Yet they make their houses in the cliff;

since they relate only to food and drink and various washings, requirements for the body imposed until a time of reformation.
