1 Corinthians 7:37-39

New Catholic Bible

³⁷ However, if he stands firm in his resolve and is under no obligation and, being free to carry out his will, decides in his heart to keep his virgin, he also does well. ³⁸ Therefore, the man who gives her in marriage does well, and the one who does not give her in marriage does better.

³⁹ A wife is bound to her husband as long as he lives. But should the husband die, she is free to marry anyone she wishes, only let it be in the Lord.
