Ruth 1:12
Turn again, my daughters, go your way; for I am too old to have an husband. If I should say, I have hope, if I should have an husband also to night, and should also bear sons; Turn again, my daughters, go your way; for I am too old to have an husband. If I should say, I have hope, if I should have an husband also to night, and should also bear sons;
About ten years before, famine in Israel drove Naomi with her husband Elimelech and their two sons Mahlon and Chilion from Bethlehem to live in Moab, where the sons married Orpah and Ruth. After Elimelech and both sons died, Naomi decided to return to Bethlehem because she heard conditions were prosperous there, with the two young widows at first setting out with her. The verse is one of Naomi's arguments urging her widowed daughters-in-law Orpah and Ruth to turn back and remain with their own people in Moab rather than leave Moab to go with her to Bethlehem.
She tells them she is too old to marry again and has no more sons to become their husbands, so she cannot offer them any realistic hope of new husbands and sons through her. She adds the hypothetical that even if she were to marry that very night and bear sons, the young widows could not reasonably wait for those sons to grow up to provide husbands for them. Her age and sonlessness mean she has no human way to hold the family inheritance and preserve the family name, so the hypothetical hope of marrying and bearing sons only highlights her apparent lack of a way forward.
She presents this lack of any temporal advantage and the hardship of accompanying her to press them to consider their future, holding up return to Moab as the practical and better prospect for their earthly welfare. In urging them to turn back she expresses deep grief for their sakes because the hand of the Lord has gone out against her. Orpah acts on the appeal and returns, while Ruth's steadfast refusal to leave Naomi or turn back to Moab and its gods stands against it. Ruth's choice to go with Naomi gives Naomi a last ray of hope because she still has kinsmen in Bethlehem.
The verse belongs to Ruth's story, a beautiful account of simple home life among the children of Israel showing God's care for the promised Seed, in which Ruth the Moabitess became one of the ancestors of Christ according to the flesh.
