Bible Verses About Mother-in-Law: Not to be defiled

Thou shalt not uncover the nakedness of a woman and her daughter, neither shalt thou take her son's daughter, or her daughter's daughter, to uncover her nakedness; for they are her near kinswomen: it is wickedness.

And if a man take a wife and her mother, it is wickedness: they shall be burnt with fire, both he and they; that there be no wickedness among you.

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