Ephod \Eph"od\, n. [Heb. ?????, fr. '[=a]phad to put on.] (Jew.
   Antiq.)
   A part of the sacerdotal habit among Jews, being a covering
   for the back and breast, held together on the shoulders by
   two clasps or brooches of onyx stones set in gold, and
   fastened by a girdle of the same stuff as the ephod. The
   ephod for the priests was of plain linen; that for the high
   priest was richly embroidered in colors. The breastplate of
   the high priest was worn upon the ephod in front. --Exodus
   xxviii. 6-12.
