Deuteronomy 22:15-17

15Then the woman’s father and mother must bring the proof of her virginity to the elders as they hold court at the town gate.

16Her father must say to them, ‘I gave my daughter to this man to be his wife, and now he has turned against her.

17He has accused her of shameful conduct, saying, “I discovered that your daughter was not a virgin.” But here is the proof of my daughter’s virginity.’ Then they must spread her bed sheet before the elders.
