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

Thou shalt not discouer the shame of the wife and of her daughter, neither shalt thou take her sonnes daughter, nor her daughters daughter, to vncouer her shame: for they are thy kinsfolkes, and it were wickednesse.

Likewise he that taketh a wife and her mother, committeth wickednesse: they shall burne him and them with fire, that there be no wickednes among you.

Cursed be he that lyeth with his mother in law: And all the people shall say: So be it.
