* a thousand.
   Twelve thousand in all--a small number in proportion to all
   Israel, or to the forces which they had to encounter.  As they
   were under the conduct of captains of thousands and hundreds,
   they probably had no general; for Phinehas seems to have
   accompanied them simply to take charge of "the holy
   instruments;" probably the ark and silver trumpets.

 * Phinehas.
