This Chapter Verse Commentaries:
Four methods of threshing are here mentioned, by different instruments; the flail, the drag, the wain, and the treading of the cattle. The staff or flail was used for the infirmiora semina, says Jerome, the grain that was too tender to be treated in the other methods. The drag consisted of a sort of strong planks, made rough at the bottom, with hard stones or iron; it was drawn by horses or oxen over the corn sheaves spread on the floor, the driver sitting upon it. Kempfer has given a print representing the manner of using this instrument, Amaen. Exot. p. 682, fig. 3. The wain was much like the former; but had wheels with iron teeth, or edges like a saw: Ferrata carpenta rotis per medium in serrarum modum se volventibus. Hieron. in loc. From this it would seem that the axle was armed with iron teeth or serrated wheels throughout. See a description and print of such a machine used at present in Egypt for the same purpose in Niebuhr’s Voyage en Arabie, Tab. 17 p. 123; it moves upon three rollers armed with iron teeth or wheels to cut the straw. In Syria they make use of the drag, constructed in the very same manner as above described; Niebuhr, Description de l’Arabie, p. 140. This not only forced out the grain, but cut the straw in pieces for fodder for the cattle; for in the eastern countries they have no hay. See Harmer’s Observ. 1 p. 425. The last method is well known from the law of Moses, which “forbids the ox to be muzzled, when he treadeth out the corn;” Deu 25:4.
