16The young woman’s father will say to the elders, ‘I gave my daughter to this man as a wife, but he hates her.

17He has accused her of shameful conduct, saying, “I didn’t find any evidence of your daughter’s virginity,” but here is the evidence of my daughter’s virginity.’ They will spread out the cloth before the city elders.
