Deuteronomy 14:3-8

3“You shall not eat anything that is detestable [to the Lord and forbidden by Him].

4These are the animals that you may eat: the ox, the sheep, the goat,

5the deer, the gazelle, the roebuck, the wild goat, the ibex, the antelope and the mountain sheep.

6Among the animals, you may eat any animal that has the divided hoof [that is, a hoof] split into two parts [especially at its distal extremity] and that chews the cud.

7However, you are not to eat any of these [animals] among those which chew the cud, or among those that divide the hoof in two: the camel, the hare and the shaphan, for though they chew the cud, they do not split the hoof; they are unclean for you.

8The swine, because it has a divided hoof but does not chew the cud; it is unclean for you. You shall not eat their meat nor touch their carcasses.
