Комментарий к Вайикра 11:4

ממעלי הגרה זממפריסי הפרסה, of those which chew the cud or only part the hoof, etc. According to Bechorot 6 the apparent duplication in these words is to teach that if an unborn animal which has parted hooves and chews the cud is found inside a mother-animal which belongs to a forbidden category, such an unborn animal may not be eaten. However, the plain meaning of the verse is as follows: the words "of the ones which chew the cud" i.e. the camel, or of "the ones which part the hoof," i.e the pig. The letter ו is not a conjunctive letter but has the same meaning as או, "or."

For he chews his cud. Why does the Torah always begin with their sign of purity first? The explanation is because their pure sign adds extra impurity to their impurity, as we find that Chazal compared Esov to a pig that sticks out its hoofs when it lies down to make it appear as if it is kosher, but its innards are full of deceit. This represents anyone whose inside is not like his outside, in the manner of the hypocrites … Therefore, the pig’s split hoof is a sign of impurity because the split hoof can deceive people and make it appear as if it is kosher.

אך את זה לא תאכלו ממעלי הגרה וממפריסי הפרסה .“however only the following you must not eat even though they either have cleft hooves or are chewing the cud;” the reason that the animals mentioned now are forbidden is that they possess only one of the two distinguishing marks mentioned in the previous verse. For instance: the pig, the camel and the hare and rabbit. The Torah did not have to spell out that animals which do not possess even one of the above distinguishing features are also forbidden. Most of them are not even considered as worthwhile eating by the gentile nations (because they are predators and their meat is not tasty). (B’chor shor)
