Leviticus 18:10

8The nakedness of thy father’s wife shalt thou not uncover: it is thy father’s nakedness.

9The nakedness of thy sister, the daughter of thy father, or daughter of thy mother, whether she be born at home, or born abroad, even their nakedness thou shalt not uncover.

10The nakedness of thy son’s daughter, or of thy daughter’s daughter, even their nakedness thou shalt not uncover: for theirs is thine own nakedness.

11The nakedness of thy father’s wife’s daughter, begotten of thy father, she is thy sister, thou shalt not uncover her nakedness.

12Thou shalt not uncover the nakedness of thy father’s sister: she is thy father’s near kinswoman.
