'Daughters' in the Bible

So she and her daughters-in-law got ready to go back from the country of Moab, for news had come to her in the country of Moab that the Lord, in mercy for his people, had given them food.

And she went out of the place where she was, and her two daughters-in-law with her; and they went on their way to go back to the land of Judah.

And Naomi said to her two daughters-in-law, Go back to your mothers' houses: may the Lord be good to you as you have been good to the dead and to me:

But Naomi said, Go back, my daughters; why will you come with me? Have I more sons in my body, to become your husbands?

Go back, my daughters, and go on your way; I am so old now that I may not have another husband. If I said, I have hopes, if I had a husband tonight, and might have sons,

Would you keep yourselves till they were old enough? would you keep from having husbands for them? No, my daughters; but I am very sad for you that the hand of the Lord is against me.
