Leviticus 11:3 - Matthew Poole's English Annotations on the Holy Bible

Cloven-footed, to wit, is divided into two parts only, as in the coney, swine, &c., whereas the horse, camel, &c. have their hoofs entire and undivided. This clause is added only to explain and limit the former, as appears from Leviticus 11:26; for the feet or hoofs of dogs, cats, &c. are parted or cloven into many parts. Cheweth the cud, Heb. and bringeth up the cud, i.e. the meat once chewed out of the stomach into the mouth again, that it may be chewed a second time for better concoction. And this branch is to be joined with the former, both properties being necessary for the allowed beasts. But the reason hereof must be resolved into the will of the lawgiver; though interpreters guess that God would hereby signify their duties by the first, that of dividing the word of God aright, and discerning between good and evil, between God's institutions and men's inventions; and by the latter, that duty of recalling God's word to our minds, and serious meditation upon it.
