1 Corinthians 7:36-37

36But if any man thinks he is behaving improperly toward his virgin, if she is past the flower of youth, and thus it must be, let him do what he wishes. He does not sin; let them marry.

37Nevertheless he who stands steadfast in his heart, having no necessity, but has power over his own will, and has so determined in his heart that he will keep his virgin, does well.
