'Mother in law' in the Bible

And they lifted up their voices and cried again. And Orpah kissed her mother-in-law [goodbye], but Ruth clung to her.

And Boaz answered and said to her, "All that you have done for your mother-in-law after the death of your husband was fully told to me. [How] you left your father and mother and the land of your birth, and you went to a people that you did not know {before}.

And she picked [it] up and went [to] the town. Her mother-in-law saw how much she had gleaned. And she took [it] out and gave to her what she had left over {after being satisfied}.

And her mother-in-law said to her, "Where did you glean {today} and where did you work? May he [who] took notice of you be blessed." And she told her mother-in-law {with whom she had worked} and said, "The name of the man who I worked with today [is] Boaz."

So she stayed close with the maidservants [of] Boaz to glean until the end of the barley harvest and wheat harvest. And she lived with her mother-in-law.

Now Naomi her mother-in-law said to her, "My daughter, should I not seek for you security that [things] may be good for you?

And she went down to the threshing floor and did all that her mother-in-law had instructed her.

And she came to her mother-in-law, and she said, "{How did it go for you,} my daughter?" And she told her all that the man did for her.

And she said, "These six measures of barley he gave to me, for he said, 'You shall not go empty-handed to your mother-in-law.'"
