Leviticus 18:12-17

12You are not to uncover the nakedness of your father’s sister, for she is your father’s direct relative.

13You are not to uncover the nakedness of your mother’s sister, for she is your mother’s direct relative.

14You are not to uncover the nakedness of your father’s brother by approaching his wife, for she is your aunt.

15You are not to uncover the nakedness of your daughter-in-law, for she is your son’s wife. You are not to uncover her nakedness.

16You are not to uncover the nakedness of your brother’s wife, because that is your brother’s nakedness.

17You are not to uncover the nakedness of both a woman and her daughter. You are not to take her son’s daughter, or her daughter’s daughter, to uncover her nakedness, for they are direct relatives. That is wickedness.
