Shamgar is mentioned only twice in the bible, Judges 3:31 and an oblique reference in Judges 5:6.

It is striking in that certain facts are made completely plain such as the number of Philistines he slew, his weapon of choice, and the presumable fact that the roads were unsafe, but no other information about him was recorded.

Are there any hermenuetical approaches that can be utilized to give a better understanding of why the information was so tersely recorded?
