Ye Shall Not Do After Their Doings — Leviticus 18:13–18

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

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

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

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

Thou shalt not uncover the nakedness of a woman and her daughter; thou shalt not take her son's daughter, or her daughter's daughter, to uncover her nakedness; they are near kinswomen: it is wickedness.

And thou shalt not take a wife to her sister, to be a rival to her, to uncover her nakedness, besides the other in her life-time.
