'Daughters in law' in the Bible

So she decided to return home from the region of Moab, accompanied by her daughters-in-law, because while she was living in Moab she had heard that the Lord had shown concern for his people, reversing the famine by providing abundant crops.

Now as she and her two daughters-in-law began to leave the place where she had been living to return to the land of Judah,

Naomi said to her two daughters-in-law, "Listen to me! Each of you should return to your mother's home! May the Lord show you the same kind of devotion that you have shown to your deceased husbands and to me!

They sacrifice on the mountaintops, and burn offerings on the hills; they sacrifice under oak, poplar, and terebinth, because their shade is so pleasant. As a result, your daughters have become cult prostitutes, and your daughters-in-law commit adultery!

I will not punish your daughters when they commit prostitution, nor your daughters-in-law when they commit adultery. For the men consort with harlots, they sacrifice with temple prostitutes. It is true: "A people that lacks understanding will come to ruin!"
