Deuteronomy 14:3-10

Do not eat any detestable thing. These are the animals you may eat: the ox, the sheep, the goat, the deer, the gazelle, the roe deer, the wild goat, the ibex, the antelope and the mountain sheep. You may eat any animal that has a divided hoof and that chews the cud. However, of those that chew the cud or that have a divided hoof you may not eat the camel, the rabbit or the hyrax. Although they chew the cud, they do not have a divided hoof; they are ceremonially unclean for you. The pig is also unclean; although it has a divided hoof, it does not chew the cud. You are not to eat their meat or touch their carcasses. Of all the creatures living in the water, you may eat any that has fins and scales. But anything that does not have fins and scales you may not eat; for you it is unclean.
