39.  coat  of  fine  linen--a garment fastened  at  the  neck,  and  
  reaching  far  down  the  person,  with  the  sleeves  terminating  at  the  
  elbow.
  
         
  girdle  of  needlework--a  piece  of  fine  twined  linen,  richly  
  embroidered,  and  variously  dyed.  It  is  said  to  have  been  very  long,  and  
  being  many  times  wound  round  the  body,  it  was  fastened  in  front  and  the  
  ends  hung  down,  which,  being  an  impediment  to  a priest in  active  duty,  
  were  usually  thrown  across  the  shoulders.  This  was  the  outer  garment  of  
  the  common  priests.
