Leviticus 18:14-16

New Revised Standard Version, Anglicised Catholic Edition

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. ¹⁶ You shall not uncover the nakedness of your brother’s wife; it is your brother’s nakedness.
