Ruth 1:11

‘ And Naomi said, “Turn again, my daughters. Why will you go with me? Have I yet sons in my womb, that they may be your husbands?”

But Naomi recognised that she now had nothing to offer them. To women of those days almost nothing was more important than having a husband and producing children. And her problem was, how could she provide them with husbands, for she had no sons in her womb. In other words she was too old to bear children. And where would Moabite women otherwise find husbands in Israel apart from in the family?
