Leviticus 18:6-8

Revised Standard Version Catholic Edition

⁶ “None of you shall approach any one near of kin to him to uncover nakedness. I am the Lord. ⁷ You shall not uncover the nakedness of your father, which is the nakedness of your mother; she is your mother, you shall not uncover her nakedness. ⁸ You shall not uncover the nakedness of your father’s wife; it is your father’s nakedness.
