Deuteronomy 14:3-10

“You shall not eat any detestable thing. These are the animals which you may eat: the ox, the sheep, the goat, the deer, the gazelle, the roebuck, the wild goat, the ibex, the antelope and the mountain sheep. Any animal that divides the hoof and has the hoof split in two and chews the cud, among the animals, that you may eat. Nevertheless, you are not to eat of these among those which chew the cud, or among those that divide the hoof in two: the camel and the rabbit and the shaphan, for though they chew the cud, they do not divide the hoof; they are unclean for you. The pig, because it divides the hoof but does not chew the cud, it is unclean for you. You shall not eat any of their flesh nor touch their carcasses. “These you may eat of all that are in water: anything that has fins and scales you may eat, but anything that does not have fins and scales you shall not eat; it is unclean for you.
