'Virgin' in the Bible

Amnon was so frustrated because of his [half-] sister Tamar that he made himself sick, for she was a virgin, and Amnon thought it impossible for him to do anything to her.

Now Tamar was wearing a [long-sleeved] robe of various colors; for that is how the virgin daughters of the king dressed themselves in robes. Then Amnon’s personal servant took her out and bolted the door behind her.
