Judges 20 (résumé): Civil War

The result of the abominable happenings with the concubine in the previous chapter was full-scale civil war in Israel. For as the word spread about the concubine's murder Israel united to punish the city of Gibeah and the Benjamites. Israel demanded that the men who committed the heinous crime be surrendered to face capital punishment, but the Benjamites refused. 

There therefore ensued a series of battles between Israel as a whole, versus the Benjamites, with initially the latter prevailing killing 40,000 men. However in the third battle things were inverted with Israel defeating Benjamin killing 25,100 men and taking and burning the city of Gibeah. They then went on to take and burn the surrounding towns and villages with just 600 Benjamin fighters surviving.
