Deuteronomy 22:15-17

15Then the father and mother of the young woman must produce the evidence of virginity for the elders of the city at the gate.

16The young woman’s father must say to the elders, “I gave my daughter to this man and he has rejected her.

17Moreover, he has raised accusations of impropriety by saying, ‘I discovered your daughter was not a virgin,’ but this is the evidence of my daughter’s virginity!” The cloth must then be spread out before the city’s elders.
