열왕기상 22:24 할라카: Shulchan Arukh, Yoreh De'ah

The Signs of Pure Beasts and [Wild] Animals - 3 Paragraphs: The signs of beasts and [wild] animals are explained in the Torah, and there are two signs: It regurgitates its cud, and its hooves are split. And any beast or animal that does not have teeth in its upper jaw nor protrusions (nivim), which are mounds of flesh-like teeth that protrude from the jaws - and some say that protrusions are two teeth above, one from here and one from there (canines), at the end of the mandible - it is certain that it is pure (kosher). That is when one recognizes that it is [not] a young camel that does not have protrusions until it grows. And anything that regurgitates its cud has a split hoof except for the camel, the hare, and the daman, as they regurgitate their cud but do not have split hooves; so with them, we do not concern ourselves if they teeth above or protrusions. Hence, if one was walking in the wilderness and found an animal but does not recognize it and its hooves were cut, such that he may surely not inspect them, he may inspect it [thus]; if it has no upper front teeth, it is certainly pure. And that is if he knows it is [not] a young camel. And anything that has split hooves regurgitates its cud except for the swine. Hence, if one found an animal and its mouth was cut, such that he may surely not inspect it, he may inspect its feet. If it has hooves that are split, it is certainly pure. And that is if he knows it is [not] a swine. If it has horns, there is no longer a doubt that it is a swine, so it is pure. And there is no impure animal, the flesh of the edges of the tailbone of which runs like warp and woof (part of it stretches vertically and part of it horizontally), to whichever side it is cut beside the arod (wild donkey). Hence, if one finds an animal whose mouth and hooves are cut, such that he may surely not inspect them, he may inspect the flesh of the edges of the tailbone after he slaughters it. If it runs like warp and woof, it is pure. And that is if he knows it is [not] a wild donkey. (It is forbidden by the Torah to eat human flesh - Ran in the chapter [entitled] Af Al Pi; Rambam, Laws of Forbidden Foods 22:3 with the Maggid Mishneh; Korban Aharon, Chapter 8 64d; not like it is implied from Tosafot in the chapter [entitled] Af Al Pi and the Rosh, that human flesh is not forbidden by the Torah. And see, Bach.)
