A guy's second "wife" runs away to her parent's house, so he drags her back. They get lost traveling, so the Levite asks another man if they could stay in his house for the night. In the night, a bunch of thugs start slamming on the door, ordering the Levite to come out, so they can "know him carnally" (rape him). The second man is shocked, and offers his virgin daughter and the Levite's concubine to the thugs. They rape the concubine all night, and she falls unconscious once they finally leave at dawn. The Levite comes outside, sets her on their camel, and brings her home. She dies on the way. So the Levite cuts her up. The End.
What can be learned from this?
