'Virgins' in the Bible

Give up to destruction old men and young men and virgins, little children and women: but do not come near any man who has the mark on him: and make a start at my holy place. So they made a start with the old men who were before the house.

And they are not to take as wives any widow or woman whose husband has put her away: but they may take virgins of the seed of Israel, or a widow who is the widow of a priest.
