This caught my eye:
"Among all this people there were seven hundred chosen men lefthanded; every one could sling stones at an hair breadth, and not miss."
I look for genetic clues in the bible, not appropos to the subject under discussion.
Jdg 21:17 "And they said, [There must be] an inheritance for them that be escaped of Benjamin, that a tribe be not destroyed out of Israel.
Jdg 21:18 Howbeit we may not give them wives of our daughters: for the children of Israel have sworn, saying, Cursed [be] he that giveth a wife to Benjamin."
If you read all of chapter 21 you will see how Benjamin was regenerated. It was still the smallest tribe but Judah would not have been able to reign in Jerusalem if Benjamin had not been given to Judah as "light bearers" when teh Kingdoms were divided because Jerusalem was in the alottment of Benjamin's land.
Later in history they were called Galileans, I believe.
They were almost lost when God caused a breach but God arranged for the regeneration.
She was already dead from the abuse (Judges 19:28). What was unusual was that instead of immediate and respectful burial her body was used as a message to rally the tribes against the conduct of Benjamites.
