Leviticus 18:15

13Thou shalt not uncover the nakedness of thy mother’s sister: for she is thy mother’s near kinswoman.

14Thou shalt not uncover the nakedness of thy father’s brother, thou shalt not approach to his wife: she is thine aunt.

15Thou shalt not uncover the nakedness of thy daughter in law: she is thy son’s wife; thou shalt not uncover her nakedness.

16Thou shalt not uncover the nakedness of thy brother’s wife: it is thy brother’s nakedness.

17Thou 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.
