These shall ye not eat of them that chew the cud, &c.— Some few creatures (which were deficient in one or other of the marks above given, either not having, or not dividing the hoof, or not chewing the cud; see Houbigant's note) are excepted in these following verses from those allowed by the general rule in the 3rd verse; and of which, as other nations have commonly eaten, it may seem probable that they are forbidden only to mark the separation of the Jewish people: which is the more likely, as the camel, the first of those prohibited, was then and is still eaten by the Arabians; with whom and the Hebrews, by means of this prohibition, all familiar intercourse was cut off. However, it is observed, that though the food of this animal is only vegetables and water, yet the fibres are hardened, or rendered in a great measure indigestible, and the salts are highly exalted by its habitual exercise. The Arabian writers themselves acknowledge, as Mr. Sale tells us in his Preliminary Discourse to the Koran, that the Arabians have a natural disposition to war, bloodshed, and cruelty, being so much addicted to bear malice, that they scarcely ever forgive; which vindictive temper, some physicians say, is exceedingly increased and indulged, by their frequent feeding on camel's flesh.
