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

Thou shalt not uncover the nakedness of thy wife and her daughter. Thou shalt not take her son's daughter or her daughter's daughter, to discover her shame: because they are her flesh, and such copulation is incest.

If any man after marrying the daughter, marry her mother, he hath done a heinous crime. He shall be burnt alive with them: neither shall so great an abomination remain in the midst of you.

Cursed be he that lieth with his mother-in-law: and all the people shall say: Amen.
