Deuteronomy 22:15-17

15then the father and mother of the young woman shall take and bring out the evidence of the young woman’s virginity to the elders of the city at the gate.

16And the young woman’s father shall say to the elders, ‘I gave my daughter to this man as wife, and he detests her.

17Now he has charged her with shameful conduct, saying, “I found your daughter was not a virgin,” and yet these are the evidences of my daughter’s virginity.’ And they shall spread the cloth before the elders of the city.
