Judges 19 - 21

The chilling account of violence, murder and retribution is given.  A man travelling with his concubine escapes the advances of perverted men only to have them murder his concubine.  He sends a bloody message to the nation and rallies the troops to deal with this problem.  In the course of events, the tribe of Benjamin is almost obliterated due to their failure to deal with sin properly.  Only by God's grace is the family line preserved.  The book of Judges closes with the chilling assessment that "everyone did what was right in his own eyes."  Not a good way to manage any society.
