You shall not uncover the nakedness of your father, which is the nakedness of your mother; she is your mother, you shall not uncover her nakedness. 8You shall not uncover the nakedness of your father’s wife; it is your father’s nakedness. 9You shall not uncover the nakedness of your sister, your father’s daughter or your mother’s daughter, whether brought up in the family or in another home. You shall not uncover the nakedness of your son’s daughter or of your daughter’s daughter, for their nakedness is your own nakedness. You shall not uncover the nakedness of your father’s wife’s daughter, brought up in your father’s family, since she is your sister. You shall not uncover the nakedness of your father’s sister; she is your father’s relative. You shall not uncover the nakedness of your mother’s sister, for she is your mother’s relative.

And you shall not take a woman as a rival wife to her sister, uncovering her nakedness while her sister is still alive.

    O forgotten prostitute!
    Make sweet melody;
