Deuteronomy 22:17

And now he has accused her of shameful conduct, saying, ‘I discovered that your daughter was not a virgin.’ But here is the proof of her virginity.” And they shall spread out the cloth before the city elders.

And, lo, he hath given occasions of speech against her, saying, I found not thy daughter a maid; and yet these are the tokens of my daughter’s virginity. And they shall spread the cloth before the elders of the city.
