      Jud 20:1-7. THE LEVITE, IN A GENERAL ASSEMBLY, DECLARES HIS WRONG.

      1, 2. all . . . the congregation was gathered as one man--In consequence of the immense sensation the horrid tragedy of Gibeah had produced, a national assembly was convened, at which "the chief of all the people" from all parts of the land, including the eastern tribes, appeared as delegates.
      Mizpeh--the place of convention (for there were other Mizpehs), was in a town situated on the confines of Judah and Benjamin (Jos 15:38; 18:26). Assemblies were frequently held there afterwards (1Sa 7:11; 10:17); and it was but a short distance from Shiloh. The phrase, "unto the Lord," may be taken in its usual sense, as denoting consultation of the oracle. This circumstance, together with the convention being called "the assembly of the people of God," seems to indicate, that amid the excited passions of the nation, those present felt the profound gravity of the occasion and adopted the best means of maintaining a becoming deportment.
