Amplified Bible, Classic Edition

⁷ The nakedness of your father, which is the nakedness of your mother, you shall not uncover; she is your mother; you shall not have intercourse with her.

⁸ The nakedness of your father’s wife you shall not uncover; it is your father’s nakedness.

⁹ You shall not have intercourse with or uncover the nakedness of your sister, the daughter of your father or of your mother, whether born at home or born abroad.
