Behold, here is my daughter a virgin, and his concubine; them I will bring out now, and humble you them, and do with them what seems good to you: but to this man don't do any such folly.
The writer called the Levite the "master" of the concubine in Judges 19:26 rather than her husband. Perhaps he did so because the Levite treated her as his property rather than as a person.
