* shalt not.
   In Judea, as well as in Egypt, Greece, and Italy, they made
   use of beeves to tread out the corn; and the same mode of
   threshing still obtains in Arabia, Barbary, and other eastern
   countries, to the present day.  The sheaves lie open and
   expanded on the threshing floors, and the cattle continually
   move round them, and thus tread out the grain.  The natives of
   Aleppo still religiously observe the ancient humane practice,
   inculcated by this law, of permitting the oxen to remain
   unmuzzled when treading out the corn.
