'Daughters' in the Bible

Naomi said, "Go back, my daughters. Why do you want to go with me? Do I still have sons in my womb, that they may be your husbands?

Go back, my daughters, go your way; for I am too old to have a husband. If I should say, 'I have hope,' if I should even have a husband tonight, and should also bear sons;

would you then wait until they were grown? Would you then refrain from having husbands? No, my daughters, for it grieves me much for your sakes, for the hand of Yahweh has gone out against me."
