'Daughters in law' in the Bible

She and her daughters-in-law prepared to return from the country of Moab, because she had heard while living there how the LORD had come to the aid of his people, giving them relief.

So she left the place where she had been, along with her two daughters-in-law, and they traveled along the return road to the land of Judah.

But along the way, Naomi told her two daughters-in-law, "Each of you go back home. Return to your mother's house. May the LORD show his gracious love to you, as you have shown me and our loved ones who have died.

They offer sacrifices on the mountain tops, burning offerings on the hills, under oaks, poplars, and terebinth trees, since their shade is very good. Therefore your daughters are prostitutes and your daughters-in-law commit adultery.

However, I'm not going to punish your daughters when they commit prostitution, nor your daughters-in-law when they commit adultery, because their men are themselves immoral they offer sacrifices with prostitutes. These people who aren't discerning will stumble.
