Leviticus 18:13-15

New Revised Standard Version, Anglicised Catholic Edition

¹³ You shall not uncover the nakedness of your mother’s sister, for she is your mother’s flesh. ¹⁴ You shall not uncover the nakedness of your father’s brother, that is, you shall not approach his wife; she is your aunt. ¹⁵ You shall not uncover the nakedness of your daughter-in-law: she is your son’s wife; you shall not uncover her nakedness.
