Judges 19:29-30

29And when he was come into his house, he took the knife, and laid hold on his concubine, and divided her, according to her bones, into twelve pieces, and sent her into all the borders of Israel. 30And it came to pass that every one that saw it said, There was no such deed done nor seen from the day that the children of Israel came out of Egypt to this day. Think it over, advise, and speak.
