Jamieson, Fausset & Brown, on Judg 19:29

“And when he was come home he took a sword, and divided the dead body of his wife with her bones into twelve parts, and sent the pieces into all the borders of Israel.”

“divided her . . . into twelve pieces--The want of a regular government warranted an extraordinary step; and certainly no method could have been imagined more certain of rousing universal horror and indignation than this terrible summons of the Levite. Next: Judges Chapter 20”
