But these you shall not eat of those that chew the cud or of those that have the split hoof, the cloven one: the camel, the hare, and the hyrax, for they chew the cud but do not have split hooves; they are unclean for you.
English: “But these you shall not eat of those that chew the cud or of those that have the split hoof” — this teaches concerning those that possess one sign of purity that they are forbidden by a negative commandment.
On the daf / in context: Sifrei notes that the camel, hare and hyrax each have one of the two required signs; the explicit negative commandment is therefore needed, and from them one derives the a fortiori for animals that have neither sign.
Type of Learning
Derash on the explicit negative commandment (Sifrei) — animals with a partial sign are still forbidden by a lav.
What Is Learned
Even an animal that possesses one of the two kashrut signs remains forbidden; the Torah states the lav explicitly for the partial-sign cases.
