Leviticus 18:11-15

The nakedness of your father’s wife’s daughter, born to your father, she is your sister; you shall not uncover her nakedness.

You shall not uncover the nakedness of your father’s sister; she is your father’s blood relative.

You shall not uncover the nakedness of your mother’s sister, for she is your mother’s blood relative.

You shall not uncover the nakedness of your father’s brother. You shall not approach his wife; she is your aunt.

You shall not uncover the nakedness of your daughter-in-law. She is your son’s wife; you shall not uncover her nakedness.
