Leviticus 11:6 - Ellicott's Commentary On The Whole Bible

And the hare, because he cheweth the cud, but. — Better, though he cheweth the cud, yet. Other nations, too, shunned the flesh of hares. The Parsees considered the hare as the most unclean of all animals, and the ancient Britons abstained from eating it because of the loathsome disorders to which the hare is subject. Like the rabbit, or the hyrax, the hare has not the peculiar stomach of the true ruminant; but, like the rabbit, the hare, when sitting at rest, so moves its jaws that it appears to masticate. As the object of the legislator was to furnish the people with marks by which they were to distinguish the clean from the unclean animals, he necessarily adopted those which were in common vogue, and which alone were intelligible in those days.
