'Sexual Relations' in the Bible

a man has sexual relations with her and she conceals it from her husband, keeping it secret although she has defiled herself with there being no witnesses against her, but she was caught anyway.

"The priest is to administer this oath to the woman: "If indeed another man didn't have sexual relations with you and you didn't become unfaithful to your husband, then may you be free from these waters that bring a curse.

But if you have become unfaithful to your husband and have become defiled because a man who isn't your husband has had sexual relations with you"'

While Israel was staying in the Acacia Grove, the people began to have sexual relations with the women of Moab.

So now, kill all the male children and kill every woman who has had sexual relations with a man,

but keep alive for yourselves all the young females who have not had sexual relations.

and 32,000 people, all the females who had not had sexual relations with a man.
