'Daughter in law' in the Bible

So Naomi returned, and Ruth the Moabite her daughter-in-law with her, returning from the countryside of Moab. And they came [to] Bethlehem at [the] beginning of [the] harvest of barley.

And Naomi said to her daughter-in-law, "[May] he be blessed by Yahweh, whose loyal love has not forsaken the living or the dead." And Naomi said to her, "The man is a close relative for us, he [is] one of our redeemers."

And Naomi said to Ruth her daughter-in-law, "[It is] good, my daughter, that you go out with his maidservants so that you will not {be bothered} in another field."

He shall be for you a restorer of life and a sustainer in your old age, for your daughter-in-law who loves you, who [is] better for you than seven sons, has borne him."
