'Virgin' in the Bible

And the wife is not the same as the virgin. The virgin gives her mind to the things of the Lord, so that she may be holy in body and in spirit: but the married woman takes thought for the things of the world, how she may give pleasure to her husband.

But if, in any man's opinion, he is not doing what is right for his virgin, if she is past her best years, and there is need for it, let him do what seems right to him; it is no sin; let them be married.

But the man who is strong in mind and purpose, who is not forced but has control over his desires, does well if he comes to the decision to keep her a virgin.

So then, he who gets married to his virgin does well, and he who keeps her unmarried does better.
