11You shall not uncover the nakedness of the daughter of your father's wife; she is your sister by the same father: you shall not uncover her nakedness.
12You shall not uncover the nakedness of your father's sister, for she is near akin to your father.
13You shall not uncover the nakedness of your mother's sister, for she is near akin to your mother.
14You shall not uncover the nakedness of your father's brother, and you shall not go in to his wife; for she is your relation.
15You shall not uncover the nakedness of your daughter-in-law, for she is your son's wife, you shall not uncover her nakedness.
