* two trumpets.
   The necessity of such instruments will at once appear, when
   the amazing extent of this army is considered.  There were
   various kinds of trumpets among the ancients, of different
   forms and materials, as Eustathius shews on Homer, where he
   mentions six; the second of which was [stroggule,] turned
   up round, like a ram's horn; which he says the Egyptians used
   (from being invented by Osiris) when they assembled the
   people to their sacrifices.  But in opposition to that form,
   Moses commands these to be made long, in the shape of those
   used at present.  So Josephus informs us, who says they were
   near a cubit long; the tube of the thickness of a common pipe
   or flute; the mouth no wider than just to admit blowing into
   them; and their ends wide like those of a modern trumpet.
