Deuteronomy 14:6-8

Amplified Bible

⁶ Among 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. ⁷ However, 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 ^[a]shaphan, for though they chew the cud, they do not split the hoof; they are unclean for you. ⁸ The 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.
