 * separate themselves.
   The word {yaphli,} rendered "shall separate themselves,"
   signifies, "the doing of something extraordinary," and is the
   same word as is used concerning the making a singular vow.
   (Le 27:2); it seems to convey the idea of a person's acting
   from extraordinary zeal for God and religion.

 * to vow.
  Le 27:2  Jud 13:5  1Sa 1:28  Am 2:11,12  Lu 1:15  Ac 21:23,24 
 * to separate themselves.  or, to make themselves Nazarites.
   {Lahazzir,} from {nazar,} to be separate; hence {nazir,} a
   Nazarite, i.e., a person separated; one peculiarly devoted to
   the service of God by being separated from all servile
   employments.  The Nazarites were of two kinds:  such as were
   devoted to God by their parents in their infancy, or even
   sometimes before they were born; and such as devoted
   themselves.  The former were Nazarites for life; and the
   latter commonly bound themselves to observe the laws of the
   Nazarites for a limited time.  The Nazarites for life were
   not bound to the same strictness as the others, concerning
   whom the laws relate.
