'Daughters in law' in the Bible

And she will arise and her daughters-in-law, and she will turn back from the field of Moab: for she heard in the field of Moab that Jehovah reviewed his people to give bread to them.

And she will go forth from the place where she was there, and her two daughters-in-law with her; and they will go in the way to turn back to the land of Judah.

And Naomi will say to her two daughters-in-law, Go, turn back each to the house of her mother: Jehovah will do mercy with you according as ye did with the dead, and with me.
