Shamgar, son of Anath (Hebrew שמגר בן־ענת) is the name of one or possibly two inividuals named in the Book of Judges. The name occurs twice; at the first mention Shamgar is identified as a Biblical Judge, who repelled Philistine incursions into Israelite regions, and slaughtered 600 of the invaders with an ox goad (a formidable weapon sometimes ten feet long); the other mention is within the Song of Deborah, where Shamgar is described as having been one of the prior rulers, in whose days roads were abandoned, with travelers taking winding paths, and village life collapsing.
