'Mother in law' in the Bible

Cursed be he that lieth with his mother-in-law! And all the people shall say, Amen.

And they lifted up their voice and wept again. And Orpah kissed her mother-in-law, but Ruth clave to her.

And Boaz answered and said to her, It has fully been shewn me, all that thou hast done to thy mother-in-law since the death of thy husband; and how thou hast left thy father and thy mother, and the land of thy nativity, and art come to a people that thou hast not known heretofore.

And she took it up, and came into the city, and her mother-in-law saw what she had gleaned; and she brought forth and gave to her that which she had reserved after she was sufficed.

And her mother-in-law said to her, Where hast thou gleaned to-day? and where hast thou wrought? Blessed be he that did regard thee! And she told her mother-in-law with whom she had wrought, and said, The man's name with whom I wrought to-day is Boaz.

So she kept with the maidens of Boaz to glean, until the end of the barley-harvest and of the wheat-harvest. And she dwelt with her mother-in-law.

And Naomi her mother-in-law said to her, My daughter, shall I not seek rest for thee, that it may be well with thee?

And she went down to the floor, and did according to all that her mother-in-law had bidden her.

And she came to her mother-in-law; and she said, Who art thou, my daughter? And she told her all that the man had done to her.

And she said, These six measures of barley gave he me; for he said to me, Go not empty to thy mother-in-law.

For the son dishonoureth the father, the daughter riseth up against her mother, the daughter-in-law against her mother-in-law: a man's enemies are the men of his own household.
