Deuteronomy 22:15-17

15If that happens, the woman's parents must bring the cloth that she slept on with her husband. They must take it to the leaders of the town to show them.

16The woman's father must say to the leaders, ‘I gave my daughter to this man to be his wife. But now he does not like her.

17He accuses her that she is bad. He says, “I discovered that your daughter had sex before I married her.” But look at her cloth. This shows that she had never had sex before.’ Then her parents must hold the cloth in front of the leaders of the town.
