Leviticus 18:9-11

New King James Version

^9 (A)The nakedness of your sister, the daughter of your father, or the daughter of your mother, whether born at home or elsewhere, their nakedness you shall not uncover. ¹⁰ The nakedness of your son’s daughter or your daughter’s daughter, their nakedness you shall not uncover; for theirs is your own nakedness. ¹¹ The nakedness of your father’s wife’s daughter, begotten by your father—she is your sister—you shall not uncover her nakedness.
