'Daughters in law' in the Bible

And she arose, she and her daughters-in-law, and returned from the fields of Moab; for she had heard in the fields of Moab how that Jehovah had visited his people to give them bread.

Wherefore she went forth out of the place where she had been, and her two daughters-in-law with her; and they went on the way to return to the land of Judah.

And Naomi said to her two daughters-in-law, Go, return each to her mother's house. Jehovah deal kindly with you, as ye have dealt with the dead and with me.
