'Mother in law' in the Bible

They began to cry loudly again. So Orpah kissed her mother-in-law good-bye, but Ruth remained with her.

Boaz answered her, "It has been clearly disclosed to me all that you have done for your mother-in-law following the death of your husband how you abandoned your father, your mother, and your own land, and came to a people you did not previously know.

and she taketh it up, and goeth into the city, and her mother-in-law seeth that which she hath gleaned, and she bringeth out and giveth to her that which she left from her satiety.

Her mother-in-law noticed how much Ruth had gleaned and had brought back from what was left over from her lunch. So her mother-in-law quizzed her, "Where did you glean today? Where, precisely, did you work? May the one who took notice of you be blessed." So Ruth told her mother-in-law with whom she had worked. She said, "The man's name with whom I worked today is Boaz."

So Ruth continued to stay close to the young women who worked for Boaz, gathering grain until both the barley and wheat harvests were complete, all the while living with her mother-in-law.

Ruth's mother-in-law Naomi, told her, "My daughter, should I not make inquiries about your financial security, so you'll be better off in life?

So she went out to the threshing floor and did precisely what her mother-in-law had advised.

When Ruth returned to her mother-in-law, Naomi asked her, "How did it go, my daughter?"

Then she related everything that the man had done for her. Ruth also said, "He gave me these six units of barley and told me, "Don't go back to your mother-in-law empty-handed.'"
