What does Judges 19:7 mean?

A man's attempt to pick up his runaway concubine (Judges 19:1–4) has turned into a kind of social comedy revolving around manners. The Levite came to his unfaithful concubine's family home with every intention to be kind to her. His goal was to take her back to his home in Ephraim. Both she and her father have seemed happy that he has come.

They couple has stayed for three days and enjoyed her father's hospitality. The Levite woke up early on the fourth day to get on the road back home, but the woman's father insisted he have a quick bite before leaving (Judges 19:5–6). That brief meal turned into eating and drinking for a while until the father said, "Why don't you stay another night and leave tomorrow?"

The Levite now tries to refuse. He is ready to go. He gets up to leave. He cannot, though, resist his father-in-law's insistence that he stay just one more day and night. So, the Levite and his concubine stay another night.
