1 Corinthians 7:37-39

Revised Standard Version

³⁷ But whoever is firmly established in his heart, being under no necessity but having his desire under control, and has determined this in his heart, to keep her as his betrothed,^[a] he will do well. ³⁸ So that he who marries his betrothed^[b] does well; and he who refrains from marriage will do better.

³⁹ A wife is bound to her husband as long as he lives. If the husband dies, she is free to be married to whom she wishes, only in the Lord.
